摘要
描述了一种对于包获取的自适应门限控制方案 ,该方案根据噪声电平的最大似然估计自适应的设置判决门限 ,并对其性能进行了分析。通过和其它的包获取的门限控制方案的对比 。
An adaptive threshold control scheme for packet acquisition is described In this scheme,the decision threshold is adaptively set according to the ML estimate of the noise power and the performance of this scheme is analyzed Through the comparison between this scheme and other threshold control scheme for packet acquisition,the advantage of this scheme is shown
