摘要：
In this work we propose a wideband spectrum sensing system based on hybrid filter banks. The polyphase implementation of the digital counterpart of the filter bank can be modified to include a parallelized version of discrete Fourier transform algorithm (FFT) avoiding this way any sampling rate expanders. In this work we show how to incorporate the FFT block in the structure in order to estimate the wideband frequency contents of the signal. The proposed structure is particularly suitable for FPGA based implementations.
