We consider the following channel-splitting problem: it is required to split a B-bits/s speech-code sequence into two “self-contained” B/2-bits/s components, either of which can be used to reproduce acceptable speech; also, if both components are available at a receiver, it must be possible to reproduce speech with full B-bits/s quality. We propose a solution where for interesting values of B, the speech quality resulting from half-rate receptions approximately equals that from conventional… CONTINUE READING
