摘要
首先介绍了实信号的多相滤波信道化体制,讨论了该体制下宽带信号跨信道接收时的信号检测技术以及邻信道虚假信号消除技术。然后详细讨论了各种跨信道宽带信号恢复算法,考虑到可行性和FPGA的硬件可实现性,选用综合滤波器算法进行宽带接收。最后通过MATLAB仿真验证算法的有效性。
Firstly,the channelized receiver system based on the polyphase filter with the real signal input is introduced.Then with the system,the signal detection technology of the crossing channels reception of broadband signals and the technology of adjacent-channel false signals elimination are discussed.Various crossing channel broadband signal recovering algorithms are discussed.According to the feasibility and FPGA hardware requirements,comprehensive filter algorithm is selected.Finally MATLAB simulations verify the algorithm.
