Digital demodulation techniques for radio channels

Bridges, Paul A (1993) Digital demodulation techniques for radio channels. Coursework Master thesis, Victoria University of Technology.


The basis of this research is directed towards the Private Mobile Radio (PMR) networks, which play significant roles in taxi, police, ambulance and other such services. With an ever increasing need for data transmission, the current PMR systems which were designed for voice are not adequate. This research will examine a digital modulation scheme which can co-exist with an analog system. The generation of the digital modulation will be examined in terms of Adjacent Channel Interference (ACI) requirements. Simulation techniques for the mobile radio channel are discussed, for evaluation of demodulator performance. Existing demodulation techniques were reviewed, with several of these simulated to find the most appropriate demodulation scheme for this application. This included the development of a new detection scheme. A test system using Digital Signal Processing (DSP) techniques was constructed.
