Abstract
A technique for increasing the efficiency of an ARQ system using time diversity reception is proposed fo mobile radio use. In this technique, the receiver demodulator output associated with each symbol is weighted and combined every time a new retransmission is made. Theoretical results show that this technique offers a considerable reduction in the average number of transmissions, in comparison with conventional ARQ systems.
