Abstract

A spread spectrum PRMA (SSPRMA) is proposed. We analyze its average data packet access delay (Dav) and the probability of voice packet being dropped (Pdrop) by computer simulation. Numerical results prove that SSPRMA enjoys a higher statistical multiplexing gain, however, the performance of SSPRMA suffers drastic deterioration under heavy load conditions. A modified SSPRMA named minimum reservation capacity SSPRMA (MSSPRMA) is proposed to alleviate the drastic deterioration. Simulation results prove that MSSPRMA is very effective in alleviating the drastic deterioration of performance of SSPRMA
