适用于多天线***的阻塞信号配置方法及装置Blocking signal configuration method and device suitable for multi-antenna system 技术领域Technical field
本发明涉及无线通信技术领域，尤其涉及一种适用于多天线***的阻塞信号配置方法及装置。The present invention relates to the field of wireless communication technologies, and in particular, to a blocking signal configuration method and apparatus suitable for a multi-antenna system.
背景技术Background technique
随着无线通信技术的不断发展，无线通信***的使用率也越来越高。其中，多天线(Multiple-Input Multiple-Output，多入多出技术)***为无线通信***中比较常用的***之一。多天线***中的发送端和接收端通过合法信道进行通信，由于多天线***中发送端和接收端均采用多根天线，通过利用多根天线，产生一个具有一定方向性的波束，通过将发射能量集中在某个特定的传输方向，来增加接收信号功率，并减少与其他用户间的阻塞，达到增强接收端抗阻塞的目的。虽然目前对于多天线***中的抗阻塞技术已经得到广泛的研究，但是对多天线***中的阻塞技术研究的较少，其中，阻塞技术即通过主动阻塞目标对象发送方与接收端之间的通信过程，实现主动防御的技术，因此如何实现多天线***中的阻塞技术为已经成为重要研究问题之一。With the continuous development of wireless communication technologies, the usage rate of wireless communication systems is also increasing. Among them, the multiple-input multiple-output (Multi-input Multiple-Output) system is one of the more commonly used systems in wireless communication systems. The transmitting end and the receiving end in the multi-antenna system communicate through a legal channel. Since the transmitting end and the receiving end use multiple antennas in the multi-antenna system, a plurality of antennas are used to generate a beam having a certain directivity, and the transmitting is performed by using a plurality of antennas. The energy is concentrated in a specific transmission direction to increase the received signal power and reduce the blocking with other users, so as to enhance the anti-blocking effect of the receiving end. Although the anti-blocking technology in multi-antenna systems has been extensively studied at present, there are few researches on blocking techniques in multi-antenna systems, in which blocking technology actively blocks the communication between the sender and the receiver of the target object. The process of implementing active defense technology, so how to implement blocking technology in multi-antenna systems has become one of the important research issues.
目前，通常是通过对目标对象多天线信道的信道估计过程进行阻塞，实现对目标对象发送端与接收端之间的无线通信阻塞，其中，多天线信道包括发送端和接收端之间的合法信道、阻塞端与接收端之间的阻塞信道等。然而为了实现对目标对象多天线信道的信道估计过程进行阻塞，需要预先获取目标对象发送端与接收端之间的通信协议，并且，在进行信道估计和信道状态信息反馈的过程中，还需要进行准确的***同步，因此造成现有阻塞技术的局限性较高，实现难度较大。At present, the wireless communication jam between the transmitting end and the receiving end of the target object is usually implemented by blocking the channel estimation process of the multi-antenna channel of the target object, wherein the multi-antenna channel includes a legal channel between the transmitting end and the receiving end. Blocked channel between the blocking end and the receiving end. However, in order to block the channel estimation process of the target object multi-antenna channel, the communication protocol between the transmitting end and the receiving end of the target object needs to be acquired in advance, and in the process of performing channel estimation and channel state information feedback, it is also required to perform Accurate system synchronization, so the existing blocking technology has higher limitations and is more difficult to implement.

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.
本发明实施例提供的一种适用于多天线***的阻塞信号配置方法，如图1所示，所述方法包括：A method for configuring a blocking signal that is applicable to a multi-antenna system is provided in the embodiment of the present invention. As shown in FIG. 1 , the method includes:

其中，接收端为目标阻塞对象的接收端，阻塞信号功率越大，阻塞信号对于接收端的通信阻塞越强。包含有阻塞端的多天线***可以如图2所示。由于阻塞信号功率越大，接收端的信干噪比越低，而由于接收端的信干噪比越大接收端的接收效果越好，因此，本发明实施例通过直接配置阻塞信号对应的阻塞信号功率，根据该阻塞信号功率推导出最后的阻塞信号，可以有效地增大接收端阻塞信号功率，进而达到阻塞接收端通信的目的。 The receiving end is the receiving end of the target blocking object.

Deriving the last blocking signal according to the blocking signal power can effectively increase the blocking signal power of the receiving end, thereby achieving the purpose of blocking the communication of the receiving end.
102、根据所述阻塞信号功率，构建所述阻塞信号对应的自相关矩阵。102. Construct an autocorrelation matrix corresponding to the blocking signal according to the blocking signal power.
其中，阻塞端配置有一根或多根发射天线，每一根天线对应一个阻塞信号，每一个阻塞信号对应一个阻塞信号功率。The blocking end is configured with one or more transmitting antennas, and each antenna corresponds to one blocking signal, and each blocking signal corresponds to one blocking signal power.
103、根据所述阻塞信号对应的自相关矩阵配置所述阻塞信号。103. Configure the blocking signal according to an autocorrelation matrix corresponding to the blocking signal.
进一步地，将阻塞信号发送给目标阻塞对象的接收端，以实现对接收端与发送端之间的通信阻塞。Further, the blocking signal is sent to the receiving end of the target blocking object to implement communication blocking between the receiving end and the transmitting end.
