Polyphase filter bank channelizer

WebFeb 12, 2024 · A polyphase structure is derived underlining the efficiency of complex-valued subband processing, raised by a GDFT modulation. For the latter, a fast Fourier algorithm … WebIn this paper, the problem of how to realize an multi-channel receiver with various bandwidth is discussed in details. After a channel spectrum partition is given, a mathematic model of channelized receiver is derived, based on polyphase filter. Then a simulation system is designed. All the simulation results show that the presented model is valid and practical.
