Abstract :
A full digital DPSK demodulator employing bandpass subsampling to digitise the received signal at a high intermediate frequency is described. This sampling technique minimises the workload of the digital signal processor. The measured results of a prototype system indicate no loss compared with systems using standard lowpass sampling.
