A medium access control protocol for multimedia multi-code CDMA personal communication networks

Code division multiple access (CDMA) has become an attractive technique for medium access control in multimedia personal communication networks (PCN). A multi-priority medium access protocol for multimedia PCN is proposed and studied. The multimedia PCN uses H.263 implementation to transmit video data. We exploit the features of multi-code CDMA to maximize the utilization of the system capacity. A hybrid medium access control scheme is studied to include both reservation-based access and random-based access. Both forward error correction (FEC) and automatic repeat request (ARQ) schemes are used to handle video transmission error. Simulation results are presented to show how several system parameters can be tuned to achieve system performance improvement.
