Abstract :
The paper considers the application of a direct sequence code division multiple access (CDMA) scheme to a mobile meteor burst communication network. It is shown that a CDMA scheme solves the significant multiple-access problem caused by low channel diversity when remote station nodes are closely spaced. The CDMA scheme is shown to provide low waiting times and high throughput for networks of many thousands of nodes. A comparison of the CDMA scheme to a random frequency division multiple access scheme is provided where the offered traffic load, network size, system bandwidth, and interference levels are varied
