Algorithm for joint tree encoding of a speech-signal source and a discrete communications channel

I. N. Okov

Abstract


It is well known that a speech-signal source and a discrete communications channel may be encoded either separately or jointly. For separate encoding, the source encoder converts the speech signal to discrete form, and then the output signal of the encoder is encoded by a redundant interference-immune code. For joint encoding, these operations are performed simultaneously.

The present work proposes an algorithm for the joint tree encoding of a speech-signal source and a discrete communications channel on the basis of adaptive delta-modulation with delayed decision and noise-immune encoding with error detection.
