摘　　要：针对随着移动终端和业务的持续发展,企业级WLAN中采用传统的AP部署方式和信道竞争协议难以满足日益增长的吞吐量的需求的问题,本文提出了一种新的盲波束赋形与置零算法,该算法能够使得多个终端在同一时隙中进行传输,在有效提高信道利用率的前提下,同时较好地解决了通信的干扰问题,实验结果表明,本文提出的算法与传统的信道竞争协议和AP部署方式相比,能够有效减少开销并显著提高终端的吞吐率。With the continuous development of mobile terminals and business,in enterprise WLAN,user demand for throughput is gradually increasing.The traditional way of AP deployment and channel competition protocol can not satisfy the increasing communication demand.Therefore,many new methods have been put forward,such as interference alignment and combined beam forming.However,the use of these methods has certain limits and it is difficult to achieve good effect in actual use.This paper proposes a blind beam forming and nulling algorithm.This algorithm allows multiple terminals to transmit at the same time slot,on the premise of effectively improving the channel utilization rate,and better solving the problem of the interference of communication.Experimental results show that,compared with the traditional way of channel competition protocol and AP deployment,the proposed algorithm can effectively reduce the cost and improve the throughput of the terminal.
