Webamount of different filter bank approaches have been developed over last fifteen years. Among those filter banks, Cosine Modulated filter banks [1]-[3] are very popular because they are easy to implement and can provide perfect reconstruction (PR). The Discrete Fourier Transform (DFT) polyphase filter bank [4] is another popular filter bank that http://courses.itee.uq.edu.au/elec3004/2012s1/_lectures/ELEC3004.Lecture14.pdf

WebEach filter tap in the subfilter is pipelined to target the DSP sections of an FPGA. For instance, for an FFT length of 8, and an input vector size of 4, the block implements four filters. Each multiplier is shared N / M times, or twice. Each tap applies two coefficients, and the delay line is N / M –1 cycles.
