I was referring to the above pdf by xilinx on the implementation of channelizer using polyphase filter bank. The receiver portion should have FFT but the pdf mentions IFFT in both Tx and Rx. The paper by harris attached also mentions the same. How did xilinx get proper results by implementing ifft in both Tx and Rx?
I don't know how Xilinx built theirs, but when building my own I built separate forward (FFT) and reverse (IFFT) implementations. They're typically used together, however, so perhaps that's the confusion?
