Abstract

Abstract:
Wireless multiple access technology has grown over several decades, with new protocols being developed. Spread ALOHA has become one of the advanced techniques promising several advantages over existing conventional and spread spectrum based wireless systems. With spread ALOHA the wireless system becomes simpler, operationally flexible, higher in bandwidth and may accommodate high number of users [Dennis et al., 1997]. In this paper the performance, in terms of throughput and time delay, of spread ALOHA system as compared with code-division-multiple-access (CDMA) is analysed and evaluated in the presence of noise and interference. Mathematical expressions are derived to estimate the probability of error, throughput and time delay to compare both wireless systems.
