Abstract : This report is devoted to the investigation of robust and adaptive techniques for the digital reception of analogue modulated signals. The advantage of stationary-point sampling over random sampling is demonstrated for amplitude demodulation and for frequency demodulation by derivative measurement. Topics investigated include various frequency measurement techniques, nonparametric statistics and robust estimation, and adaptive Bayesian estimation. A digital FM receiver, based on measuring the time between zero crossings, was built and tested using robust estimation techniques. (Author)
