摘　　要：在输入为实信号、滤波器组为偶型排列并且50%重叠的情况下,推导出多相滤波信道化接收机的高效结构,利用Hilbert变换将0信道的实数信号变为复解析信号,然后进行CORDIC算法测相、一阶差分算法测频。通过仿真实验证明该设计方案的正确性与可行性。In case that the input is real signal ,the filter group is even-arrangement and 50% overlap-ping ,this paper educes the efficient structure of channelized receiver based on polyphase filter ,uses Hilbert transformation to transform the real signal of channel zero into plural analysis signal ,and then performs the phase measurement by CORDIC algorithm and frequency measurement by one-order difference algorithm .T he simulation results prove the correctness and feasibility of the design scheme .
