Multi-rate coding: a strategy for error control in mobile communication systems
S.A. Atungsiri, Ahmet M. KONDOZ, B.G. Evans · 1993
The mobile and personal communication systems (PCS) revolution is well underway. The major requirement of spectral efficiency in these systems often means the use of low bit rate speech and channel coders, rampant carrier frequency reuse with its associated problem of co-channel interference. The authors propose the use of multi-rate speech and channel codecs in future PCS to control the excessive channel degradations that arise from such interference. >
