Abstract :
Spread ALOHA has emerged as an advanced wireless multiple access technology 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 (Elliot, DW & Abramson, N, 1997). In this paper the performance, in terms of throughput and time delay, of spread ALOHA system as compared with code division multiple access is analyzed and evaluated in the presence of noise and interference. Mathematical expressions are derived to estimate probability of error, throughput and time delay to compare both wireless systems.
