Abstract

Code Division Multiple Access (CDMA) has become an attractive technique for medium access control in multimedia Personal Communication Networks (PCN). In this paper, 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 CDMA to maximize the utilisation of the system capacity. A random access control scheme is proposed for the mobile hosts to contend for spectrum resource. Both Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) schemes are used to handle video transmission error. Simulation results have been presented to show how several system parameters can be tuned to improve the system performance.
