Abstract :
The transmission of data on wireless links requires some means of preserving data integrity in spite of the higher error rates expected in a typical radio environment. Both the use of an appropriate forward error correction (FEC) coding and a suitable automatic repeat request (ARQ) protocol are considered for non-time critical services. Their use is reconsidered in view of the large number of simultaneously active logical connections or “sessions” in typical 3rd generation wireless data applications such as web browsing from a wireless IP terminal which may lead to storage, bandwidth and processing requirements exceeding the size and power restrictions of the receiver. The proposed framework for realization of a receiver-efficient selective-repeat mechanism with minimal overhead in combination with forward error-correction is described and quantitative guidelines are presented
