However, for decoding at least, the filterbank only uses 10-20 MHz (or perhaps lower with SIMD), so I'm not sure CUDA makes sense.

ANALYSIS FILTER BANK Consider the analysis ﬁlter bank of Fig. 1 producing K subband signals. To remove computational redundancies due to the decimation by N, a type-1 polyphase notation [6] is introduced for the analysis ﬁlters, H k (z)= N 1 X n =0 n j n): (1)

WebPolyphase Filter Bank Overview. This project contains an implementation of a Casper-style PFB. It consists of a bank of Finite Impulse Response (FIR) filters to shape the input time … A polyphase quadrature filter, or PQF, is a filter bank which splits an input signal into a given number N (mostly a power of 2) of equidistant sub-bands. These sub-bands are subsampled by a factor of N, so they are critically sampled. An important application of the polyphase filters (of FIR type) concerns the filtering and decimation of large band (and so high sample rate) input signals, e.g. coming from a high rate ADC, which can not be directly processed by an FPGA or in some ca… birthday verses for adult grandson
