Method and apparatus for time companding a digital voice signal

Alan L. Wilson; Michael W. Bright; Michelle M. Bray; Eric F. Ziolko; David Lee Weiss

Disclosed is a method and apparatus for time companding a digital voice signal wherein, single bits are periodically removed from the digital voice signal, which is then compressed thereby forming a contiguous area of removed bits. A synchronization signal is inserted into this area and the combined signal is transmitted. At the receiver, the synchronization signal is extracted and is used to synchronize the receiver. The digital voice signal is then expanded and the removed bits are predicted and replaced.
