Abstract :
This paper suggests a NAK-based selective repeat (SR) scheme for reliable data transmission in the future land-mobile communications systems supporting multimedia services. The proposed scheme is an improved version of the automatic repeat request defined in IS-707. We analyze the proposed SR under the assumption of a two-states Markov channel. The numerical results show that drastic performance improvement can be achieved at the cost of minor increase in complexity.
