摘　　要：针对接收信号带宽内存在多个不同带宽、非均匀分布的子带信号,其个数、带宽和位置具有时变性,提出一种动态信道化滤波的方法,实现了宽带信号多通道全概率实时并行接收,通过Matlab仿真结果验证了该方法的可行性。此方法对研究信号接收机具有重要的参考价值和广泛的应用前景。Aiming at the fact that there are several sub-band signals with different bandwith and uneven distribution in the received bandwidth, whose number, bandwidth and band location have the characteristic of the time-variant, a method of dynamic channelization filtering is presented, the multi-channel total probability real-time and parallel receiving of wideband signal is realized, and the feasibility of the method is proved through the Matlab simulation results. This method has an important reference value and broad application prospect in the study of signal receiver.
