Abstract :
It is necessary to apply SSB modulation to the DS/CDMA mobile communication systems in order to meet the increasing number of voice users as well as the broadband high rate data service in the future. However while the bandwidth efficiency is increased with SSB modulation, the performance gets degraded because of the increased multiple access interference. Therefore for solving this problem, SSB/BPSK-DS/CDMA with SIC is proposed and we showed that it can accommodate more capacity than the conventional BPSK-DS/CDMA with SIC
