Abstract:
A closed-form analytical expression is obtained for the output signal-to-noise ratio SNR. of differential PCM systems operating on noisy digital channels. A procedure is then proposed for maximizing SNR, by joint optimization of the quantizer, predictor, and sampling rate. Several examples are considered, including one- and two-sample feedback systems excited by speech and video Gaussian signals. The predictor used in the DPCM system is linear and time invariant, but otherwise arbitrary. Author
