Description

一种应用CCDP和XPIC微波传输的方法及装置Method and device for applying CCDP and XPIC microwave transmission 技术领域Technical field
本文涉及但不限于微波通信技术领域，尤其涉及一种应用单通道双极化(CCDP，Co-Channel Dual Polarized)和交叉极化干扰抵消器(XPIC，Cross-Polarisation Interference Counteracter)微波传输的方法及装置。The present invention relates to, but is not limited to, the field of microwave communication technologies, and in particular, to a method for transmitting microwave transmission using a single channel dual polarization (CCDP, Co-Channel Dual Polarized) and a cross-polarization interference counter (XPIC). Device.
背景技术Background technique
微波通信作为一种通信手段被广泛应用，由于业务及带宽的迅速增加，频点资源显得越来越紧俏，应用CCDP和XPIC的极化干扰抵消技术可以应用一个频点对极化方向不同的两路业务同时传输避免相互干扰，提高频点的使用效率。Microwave communication is widely used as a means of communication. Due to the rapid increase of services and bandwidth, frequency resources are becoming more and more tight. The polarization interference cancellation technology using CCDP and XPIC can apply two frequencies with different polarization directions. The road traffic is transmitted at the same time to avoid mutual interference and improve the efficiency of frequency usage.
CCDP是指在一个信道中采用水平极化波和垂直极化波传输两路信号；CCDP的2路同频微波信号是正交信号，因两路信号采用垂直正交的方式进行传输，所以二者之间不会发生干扰。CCDP refers to the use of horizontally polarized waves and vertically polarized waves to transmit two signals in one channel; two channels of the same frequency microwave signal of CCDP are orthogonal signals, because the two signals are transmitted in a vertical orthogonal manner, so two There is no interference between the people.
XPIC是配合CCDP使用的一种技术。CCDP利用两路正交的极化波传输信号实现传输容量加倍，而XPIC则用来消除两路极化波间的交叉干扰。理想情况下，CCDP的2个同频微波信号是正交信号，二者之间不会发生干扰，但在实际工程条件下，无论两个信号的正交性如何，总是要受天线交叉极化鉴别率(XPD，Cross Polarization Discrimination rate)和信道传输劣化的影响，无法避免的会存在信号之间的干扰。为了抵消这些干扰，就需要使用XPIC技术。XPIC技术的基本原理是从水平和垂直两个极化方向上接收信号，并将二者进行一定处理从而从被干扰的信号中恢复出原始信号。XPIC is a technology used in conjunction with CCDP. CCDP uses two orthogonal polarized waves to transmit signals to double the transmission capacity, while XPIC eliminates cross-talk between two polarized waves. Ideally, the two co-frequency microwave signals of CCDP are quadrature signals, and there is no interference between them. However, under actual engineering conditions, regardless of the orthogonality of the two signals, they are always subject to antenna crossover. The influence of the XPD (Cross Polarization Discrimination Rate) and channel transmission degradation, unavoidable interference between signals. To counteract these interferences, you need to use XPIC technology. The basic principle of the XPIC technology is to receive signals from both the horizontal and vertical polarization directions and to process the two to recover the original signal from the interfered signals.
图1是相关技术中应用CCDP和XPIC工作流程示意图，如图1所示，CCDP和XPIC的总体工作流程中，调制解调器水平(Modem Horizontal)方向和调制解调器垂直(Modem Vertical)方向分别发送两路标识为粗线条和细线条的两路业务，两路业务通过CCDP采用正交的两路信号传输，对端接收到掺杂干扰的两路信号后通过过滤分离出干扰信号后与另一路信号抵消后恢复出原始的两路业务。 FIG. 1 is a schematic diagram of the workflow of applying CCDP and XPIC in the related art. As shown in FIG. 1 , in the overall workflow of CCDP and XPIC, the Modem Horizontal direction and the Modem Vertical direction respectively send two identifiers as The two-way service of thick lines and thin lines, the two-way service adopts orthogonal two-way signal transmission through CCDP, and the opposite end receives the two signals of doping interference, then separates the interference signal through filtering and recovers after canceling with the other signal. The original two-way business.
在同时应用CCDP和XPIC的方法进行传输时，如果一路业务的单板出现故障因天气原因接收信号变差导致无法接收并且无法向另一路提供抵消信号的情况下会导致两路业务都不可用。When the CCDP and XPIC methods are used for transmission at the same time, if the failure of the board of one service is unacceptable due to the weather due to the deterioration of the received signal and the cancellation signal cannot be provided to the other path, the two services will be unavailable.
发明内容Summary of the invention
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。The following is an overview of the topics detailed in this document. This Summary is not intended to limit the scope of the claims.

The horizontal transfer unit and the vertical transfer unit have the following attributes:
极化属性：H(水平方向)、V(垂直方向)两种属性；Polarization properties: H (horizontal direction), V (vertical direction) two properties;
伙伴属性：极化方向不同的另一路业务的传输单元的位置信息，用于传输单元之间的通信。伙伴属性用于表示互为伙伴传输单元。 Partner attribute: Location information of a transmission unit of another service with different polarization directions, used for communication between transmission units. The partner attribute is used to indicate mutual partner transmission units.
业务健康属性：健康、不健康两种状态。Business health attributes: healthy and unhealthy.
发送单元开关状态：业务所在发送端的打开或关闭状态。Transmitting unit switch status: The open or closed status of the sending end of the service.
第二步当水平方向传输单元和垂直方向传输单元的检测模块检测到该路业务持续失锁一段时间(持续一直为失锁状态，传输单元认为当前业务故障)后，关闭伙伴传输单元的射频模块，并按照时间序列产成算法生成的时间启动恢复定时器。The second step is to turn off the RF module of the partner transmission unit after the detection module of the horizontal direction transmission unit and the vertical direction transmission unit detects that the service is continuously lost for a period of time (continues to be in an unlocked state and the transmission unit considers the current service failure). And start the recovery timer according to the time generated by the time series generation algorithm.
时间序列生成算法单位可以为秒，包括：The time series generation algorithm can be in seconds, including:
T(1)＝10T(1)=10
T(n+1)＝T(n)*(n+2)(n＝1、2、3、4)T(n+1)=T(n)*(n+2)(n=1, 2, 3, 4)
T(n)＝T(n-1)(n>＝6)T(n)=T(n-1)(n>=6)
上述算法主要用于按照恢复时间间隔逐渐变长的原则按照应用需求定义的时间序列生成算法，只要可以满足上述要求的算法均可以应用于本发明实施例。The above algorithm is mainly used for generating a time series algorithm according to the application requirement according to the principle that the recovery time interval is gradually longer, as long as the algorithm that can satisfy the above requirements can be applied to the embodiment of the present invention.
第三步在恢复定时器定时到时后尝试打开业务发生故障的水平方向传输单元和垂直方向传输单元的射频模块，并通知伙伴传输单元将失锁检测时间调整为2t(持续2t一直为失锁状态，伙伴传输单元认为当前业务故障)，t到时后如果伙伴传输单元为锁定状态，故障业务恢复成功清除恢复定时器，如果t到时后伙伴传输单元为失锁状态故障业务恢复失败，关闭业务发生故障的水平方向传输单元和垂直方向传输单元的射频模块，按照时间序列重新启动恢复定时器的定时，等待下次尝试恢复工作。The third step attempts to open the radio frequency module of the horizontal transmission unit and the vertical transmission unit of the service failure after the recovery timer expires, and notifies the partner transmission unit to adjust the loss detection detection time to 2t (continuous 2t is always lost lock) Status, the partner transmission unit considers the current service fault), if the partner transmission unit is locked after t, the fault service recovery succeeds in clearing the recovery timer. If the partner transmission unit is in the lost lock state after the time t expires, the service recovery fails, and the service is closed. The radio frequency module of the horizontal transmission unit and the vertical transmission unit in which the service fails, restarts the timing of the recovery timer according to the time series, and waits for the next attempt to resume the operation.
当业务发生故障的水平方向传输单元和垂直方向传输单元检测到伙伴传输单元为锁定后打开射频模块。When the service failure occurs, the horizontal direction transmission unit and the vertical direction transmission unit detect that the partner transmission unit is locked and then turn on the radio frequency module.
也就是说，将极化方向不同的两路业务配置为两个传输单元，当H(V)传输单元检测到当前业务发生故障时H(V)方向的传输单元会自动关闭射频模块，防止其干扰V(H)方向的正常工作，H(V)传输单元关闭射频模块后，会按照特定算法(时间序列产成算法)生成的时间序列打开射频模块尝试恢复，如果业务恢复成功流程终止，如果恢复失败关闭射频模块等待下一时间点继续尝试恢复直至业务恢复成功。 That is to say, the two services with different polarization directions are configured as two transmission units. When the H(V) transmission unit detects that the current service is faulty, the transmission unit in the H(V) direction automatically turns off the RF module to prevent it. Interfere with the normal operation in the V(H) direction. After the H(V) transmission unit turns off the RF module, it will open the RF module according to the time series generated by the specific algorithm (time series generation algorithm) to try to recover. If the service recovery process is terminated, if Recovery failure The RF module is shut down and waits for the next time to continue to try recovery until the service is successfully restored.
