摘要
提出了一种新的传输功率控制算法(TPC),该算法能够根据信道的自身干扰情况,自适应的优化算法参数,动态控制AP发射功率,在现有的信道资源下提升系统容量。给出了算法处理过程的描述,并以IEEE802.11b系统为例进行仿真。仿真结果表明:该算法能够实现在高密度、负载不均衡的WLAN环境下大大提高整个系统的吞吐量。
In this paper, a new Transmit Power Control algorithm is introduced in detail. TPC algorithm can optimize the parameters and adjust transmit power dynamically, according to the degree of self-interference. Thus it can improve the system capacity adaptively. The paper gives the process of this algorithm and simulates it in WLAN. The result of simulation indicates that TPC can improve total throughput in a dense and non-uniform load WLAN system.
