Abstract :
An asynchronous multicode multicarrier code-division multiple-access (CDMA) scheme for the uplink of wireless communication systems is considered in order to support multimedia services. The uncoded bit error rate of the system is analyzed after taking account of the intercarrier interference due to time-varying fading channels, inter-code interference due to the multicode assignment, and multiple access interference. Numerical results indicate that the system performance is improved with increasing the number of parallel data substreams and the processing gain. The two parameters have to be sufficiently large for supporting multimedia services.
