Multistage Multirate Filterbank for FPGA Resource Optimization
Horacio Arnaldi · IEEE Embedded Systems Letters · 2023
In this paper the problem of optimization of multirate filterbanks is addressed. The factors that define the efficiency of these multirate systems are investigated and the implementations of structures in stages are analyzed. The latter, together with the polyphase implementations of the filters, allows obtaining optimal filterbanks in the use of resources for the FPGAs.
