Abstract :
Performance of the access channel in cdma2000 and random access channel in W-CDMA is studied in this paper. In such systems, the accessing user can degrade the performance of existing users by introducing extra interference such as packet collision and blocking. We study how much the random access channel in W-CDMA is superior to an access channel in cdma2000 by employing a more complicated channel structure. In addition, channel occupancy, which is a measure of interference to other channel types in the system, is also investigated. Simulation is carried out to compare the performance of these channels under fixed frame error rates and varying offered load conditions
