Title: Method of and apparatus for controlling encoding rate in a telecommunication system
Inventor: KOTZIN MICHAEL D
IPC: G10L19/00
Filed: 1995-01-09
Abstract: A code division multiple access (CDMA) communicating system reduces interference by reducing the encoding rate for selected mobiles. The system (400) primarily uses link related characteristics such as, inter alia, distance measurements, physical resource power, and mobile determined noise, to determine which mobiles require an encoding rate reduction. Once determined, the encoding rate of the determined mobiles is reduced, which in turn reduces self-interference and enhances system capacity.
