Method and apparatus for controlling time diversity in telephony

摘要

A system of radio telephony in which time diversity is utilised to improve the quality of voice communication. Variable time diversity is introduced into the transmitted signal such that relatively longer time delays are present under poorer communication conditions. This variable time diversity can be produced by variable depth interleaving, or by use of at least two TDMA slots operating with sufficient time offset to de-correlate errors generated in the two channels.
