Description

一种频谱调整方法、发送端、接收端和***Spectrum adjustment method, transmitting end, receiving end and system 技术领域Technical field
本发明涉及无线局域网技术领域,尤其涉及一种频谱调整方法、发送端、接收端和***。The present invention relates to the field of wireless local area network technologies, and in particular, to a spectrum adjustment method, a transmitting end, a receiving end, and a system.
背景技术Background technique
随着日益增长的流量和近期出现的各种不同无线设备,静态信道分配已经难以满足数据流量的需求,根据对1.6GHz的频谱测量结果显示,用固定20MHz的信道只有6%的传输机会,而如果收发端可以在80MHz的信道上自由调整接入的频谱,传输机会则增加到90%以上,因此,提出了动态信道分配方法。With increasing traffic and the emergence of various wireless devices in the near future, static channel allocation has been difficult to meet the demand for data traffic. According to the 1.6 GHz spectrum measurement, only 6% of the transmission opportunities are fixed with a fixed 20 MHz channel. If the transceiver can freely adjust the access spectrum on the 80MHz channel, the transmission opportunity increases to more than 90%. Therefore, a dynamic channel allocation method is proposed.
由于频谱有限,不同的无线网络会共用同一频段。如WIFI、Bluetooth、ZigBee等,都工作在ISM 2.4GHz频段上。对于这种异构网络,通常采用带内频谱调整将一个信道(40MHz)再细粒度划分成10MHz、20MHz带宽的子信道,再将划分后的子信道分配给不同的网络,每个网络的设备在对应的信道上动态分配信道,通过带内频谱调整,通常会出现这样的情况:某个网络的信道超负载,而其他网络的信道空闲,因此,频谱利用率还是比较低。Due to the limited spectrum, different wireless networks share the same frequency band. Such as WIFI, Bluetooth, ZigBee, etc., all work in the ISM 2.4GHz band. For such a heterogeneous network, an intra-band spectrum adjustment is usually used to subdivide a channel (40 MHz) into sub-channels of 10 MHz and 20 MHz bandwidths, and then allocate the divided sub-channels to different networks, and devices of each network. Dynamically allocating channels on corresponding channels, through in-band spectrum adjustment, usually occurs when the channel of one network is overloaded and the channels of other networks are idle, so the spectrum utilization is still relatively low.
