PSK31


Abstract

This project demodulates at least two PSK31 signals with limited phase shifting.The approach begins by filtering the signal to find the peaks and interpolated to connect the maximums.


Introduction

PSK31 was developed by Peter Martinez (G3PLX) in 1998. PSK31 varies in amplitude and phase, but not frequency. This is extremely useful in amateur radio. When there is constant phase,
it is considered to be a 'one', when the phase shifts, it is a 'zero'.
