This m file models a DPSK UWB system using a delay in one leg of the mixer, correlation receiver low pass filter combination requiring no template for synching. Various waveforms are displayed throughout the system to allow the user to observe operation of the system.
FFTW, a collection of fast C routines to compute the Discrete
Fourier Transform in one or more dimensions.The fftw/ directory contains the source code for the complex transforms,
and the rfftw/ directory contains the source code for the real transforms.
I originally wrote this for a Z80 back in the early 80s. I found the source
code recently in one of the boxes of printouts I ve kept over the years. Good
thing too, since most of the work was on a CPM system using 128k 8inch floppies.
