1. A configurable direct sequence (DS) spread spectrum (SS) electronic device including:
a fast Fourier transform (FFT) module configured to:
receive an input signal;
compute an FFT of the input signal;
output n bins of frequency data having an initial frequency spacing, wherein n is an integer greater than 1, and wherein each of the n bins:
corresponds to a range of frequencies matching the initial frequency spacing; and
includes a magnitude of a complex-valued FFT output for the bin;
a frequency-domain decimation filter configured to:
utilize m bins of the n bins of frequency data from the FFT module having the initial frequency spacing, wherein m is an integer greater than 1; and
output q bins of the n bins of frequency data having a larger frequency spacing, wherein q is an integer greater than 1, and wherein q<m; and
memory configured to receive and store a portion of the n bins of frequency data.
