分析了MF-TDMA信号的作用以及特点，提出了对MF-TDMA信号进行检测的难点问题。根据MF-TDMA信号的特征，利用Simulink搭建了一个仿真平台，分别对两种模式的MF-TDMA信号进行了信号的仿真生成，提出了多路混叠MF-TDMA信号基于FICA的分离的方法，并在Matlab中加以实现。通过对分离后的各单路信号进行时频分析，得到MF-TDMA信号频率和时隙参数的估计值。

英文摘要：

Based on analysis of MF-TDMAsignal functions and characteristics, the difficult problems in detecting and estimating MF-TDMA signal described, and with simulink, a simulation platform of MF-TDMAgenerator is designed and built up according to these signal characterisctics, and the MF-TDMA signals by two modes are generated. Finally, source separation method based on FICA for multiplexing MF-TDMA signals is proposed and implemented in Matlab. By time-frequency analysis of every single terminal signal, the estimated parameters of MF-TDMA signal, including frequency and time slot, could be acquired.
