Abstract

The design of a speech and channel codec for the North American TDMA digital cellular half rate channel which meets the eligibility requirements of the Telecommunications Industry Association (TIA) contest is described. Its design objectives are largely shaped by the selection criteria. The codec has been implemented in real time on two Tiger C40 boards. Informal listening tests using this real-time hardware seem to indicate that this candidate is in close proximity to the full rate standard
