Abstract
This paper investigates the adaption of qnantizer step size in voice coding circuits. Techniques which maintain the decoder step size in the presence of channel errors have been evaluated. Graphs are presented for the comparison of error recovery performance. Practical considerations favor one algorithm, and its digital implementation has been described in the paper. Laboratory measurements of step-size error recovery and SNR performance have been included to verify the theory.
