摘要：

The novel digital channelizer based on the theory of frequency domain filter is proposed, the independent communication signals can be extracted from the satellite uplink wideband signal, and have been switching, synthesizing, and finally forming a satellite downlink wideband signal. The proposed novel digital channelizer is fit for not only scene of communication signals with equivalent bandwidth, but also scene of communication signals with different bandwidth. Numerical simulation shows that compared with the existing method, the new digital channelizer has better performance and flexibility, but also greatly reduces the computational complexity.
