摘　　要：本文根据软件无线电思想,在通用的平台上接收GM鄄SK、QPSK两个不同的调制的信号,对接收机各个部分的算法进行分析,如匹配滤波器的算法,信道参数估计,同步估计,信道均衡等,文章最后分析了软件无线电接收机应采用的硬件结构。According to the principle of software defined radio, we received tow kinds of signals with different modulation on the general hardware plat. We analyzed the algorithm of the receivers, such as matched filter, channel estimation, synchronization, equalizer and also. The structure of receiver hardware was analyzed in the end of the paper.
