Abstract

A TDMA radiotelephone system is described wherein a base station transmits a slot and a repeat of the slot to a mobile station. The mobile station selectively receives the slots, detects soft information from each of the slots, and provides a combination of the soft information to a channel decoder, such as a Viterbi decoder, for enhancing the operation of the channel decoder. In a further aspect of this invention a method is described for operating a wireless communication system includes the steps of: (a) transmitting a time slot and a repeat of the time slot to a channel; (b) receiving the time slot and the repeat of the time slot with a diversity receiver; (c) processing the received time slot and the repeat of the time slot with a first channel estimator and with a second channel estimator, respectively; and (d) performing a joint detection in accordance with a technique that minimizes a metric.
