Coherent demodulation of pilot tone single sideband with phase-locked TTIB FFSR processing

A Bateman, JP McGeehan

Research output: Contribution to journalArticle (Academic Journal)peer-review


The paper describes a simple modification to TTIB/FFSR signal processing which permits coherent demodulation of the signal. This property is fundamental to the successful operation of some data modems and extensively in mobile radio. The operation of the modified processing is independent of the variable delay introduced by the transmitter and receiver RF?IF circuitry and by the propagation path
