摘要

作为窄带网络载波感知多址(CSMA)协议的推广，作者考虑了在地面扩频分组无线网的信道接入协议中使用信道功率传感来获得性能提升的可能性。信道负载敏感被看作是一种基于在发送端测量到的干扰来估计接收端干扰的方法。要做到这一点，需要两个位置的干扰的二元概率分布函数。然后确定数据包成功的概率。由于难以用数值计算，因此编写了一个程序来模拟它。作者给出了随机网络的仿真结果。

On channel power sensing in terrestrial spread spectrum packet radio networks

The author considers the possibility of obtaining performance gains by using channel power sensing in the channel access protocol of a terrestrial spread-spectrum packet radio network as a generalization of the CSMA (carrier-sense multiple-access) protocol of narrowband networks. Channel load sensing is viewed as a method of estimating the interference at the receiver based on the interference measured at the transmitter. To do this, a bivariate probability distribution function of the interference at the two locations is required. The probability of packet success is then determined. Since it is difficult to evaluate numerically, a program was written to simulate it. The author gives simulation results for the case of a random network.<>
