ABSTRACT:
A digital variable rate demodulator within a receiver operates close to the Nyquist rate. This serves to recover correct timing and filter adjacent channels. The samples of an incoming data signal are divided into phases and combined into phase vectors. Intermediate points within a given phase vector are determined by interpolation. The data is then converted into a weighted sum for the purpose of decimating down to the baud rate. The signal-to-noise ratio is then optimized by estimating the likelihood of occurrence of a given symbol within the waveform and filtering the near Nyquist data rate down to a one sample per symbol data rate.
