Abstract

The impact of buffering and the use of a multichannel base station on the performance of a hybrid CDMA/ISMA protocol is investigated by simulation. Buffering moves the performance bottleneck from the terminal receiver link to the base station. The protocol performs best when both buffering and multiple return channels are used. The throughput and delay have been evaluated for the proposed hybrid CDMA/ISMA protocol considering packet buffering, multiple return channels, spread spectrum CDMA and p-persistent ISMA with DPSK modulation scheme for computer communications in Rayleigh fading indoor environments
