I am referring to the Xilinx application note Polyphase Filter Bank Channelizer. The receiver portion should have FFT but the pdf mentions IFFT in both Tx and Rx.
The paper by F. J. Harris, C. Dick and M. Rice, "Digital receivers and transmitters using polyphase filter banks for wireless communications," in IEEE Transactions on Microwave Theory and Techniques, vol. 51, no. 4, pp. 1395-1412, April 2003 also mentions the same.
How did Xilinx get proper results by implementing IFFT in both Tx and Rx?
