Abstract

An adaptive scheme for packet retransmission and packet. error control in DS-CDMA random access networks is presented. The system provides error correction coding (ECC) by using code redundancy into CDMA data packets and adaptive retransmission control (ARC) by using steady state Markov process. Simulation results show that packet error control can be effectively linked to ARC. A joint adaptation processing on ECC parameter and retransmission probability improves the system capacity significantly. The performance optimization is more feasible in high traffic wireless systems. The results are useful in designing such systems for deployment.
