Detection and selective smoothing of transmission errors in linear PCM

We consider detection of transmission errors in pcm by means of statistical hypothesis testing of the received quantized sequence. When errors are detected, a median filter is used to smooth waveform discontinuities. We describe two error detectors, one (cdc), based on correlation measurements, and the other (ddc), based on sample-to-sample difference measurements. While both offer s/n advantages over conventional pcm in the presence of errors, ddc is more promising both in terms of performance and simplicity of implementation.
