Filter bank analysis
WebTo implement the analysis filter bank efficiently, the channelizer uses a prototype lowpass filter. The prototype lowpass filter has an impulse response of h[n], a normalized two-sided bandwidth of 2π/M, and a cutoff frequency of π/M. M is the number of frequency bands, that is, the branches of the analysis filter bank. This value corresponds ... WebFeb 12, 2024 · 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.
