Abstract

The effect of a limited number of retransmissions is investigated for RCPT coded type I and II hybrid ARQ schemes in a DS-CDMA mobile radio. It is found by computer simulations that the type II scheme with minimum amount of parity bits transmitted in each retransmission gives the highest throughput. However if the signal energy is to be kept lowest, the best scheme depends on the maximum number of transmissions allowed: the type I scheme is the best for delay sensitive real-time applications and type II is suitable for delay tolerant applications like packet data communications.
