Abstract
AbstractA hierarchical multistage method (HMM) for digital demultiplexing of an FDM signal composed of L adjacent SCPC signals is described; L is preferably a power of two, here L=32. This HMM approach to FDM demultiplexing applies bandpass sampling and is based on the processing of complex‐valued signals by linear‐phase FIR filters, where at any stage of processing the respective signals are always oversampled by two. The simulation results fully confirm the predicted system performance. An electrical demonstration model constructed by cascading six identical specially designed signal processors is being built.
