High Performance Coder: A Possible Candidate for the GSM Half-Rate System
The authors describe their contribution to the ETSI (European Telecommunications Standards Institute) effort for a definition of a GSM (Group Special Mobile) standard half-rate coding system for the pan-European digital mobile cellular radio system. The system consists of a speech coder and a channel coder.
An overview of the speech coding algorithm is given. The results from a study of the different versions of the speech coder are described. A two-stage channel coding scheme is presented, and the performance test results are shown. An overview of the DSP implementation, computational requirements, and memory usage is also presented.<>
