文章比较了在单径加性高斯白噪声(AWGN)无衰落信道环境下,利用匹配滤波器(MF)捕获方法,对不同的门限比较判决准则对系统平均捕获时间(TMA)性能的影响进行了分析;同时给出了不同门限值时系统的平均捕获时间的仿真结果,并对结果进行讨论,得出各种门限设置准则的应用环境,为捕获系统的设计与实现提供参考.
We compares the mean SS receiver. The simulation result consideration is and discussion each threshold setting principle acquisition time resulted in different threshold setting principle in the DS/ made mainly in one-path AWGN channel,and MF acquisition is used. The of the mean acquisition time are given,and the application condition of is made, and can be given for reference in design and realization of the acquisition systems.
