Abstract :
In 3GPP W-CDMA, a random access channel (RACH) is used for random-access transmission from the user equipment. The RACH may also be used to carry short packets. The RACH transmission is based on the slotted ALOHA approach with fast acquisition indication. In this paper, the performance of the RACH channel with respect to delay and throughput is analyzed for a 19-cell omni system under fading conditions. An adaptive persistence control algorithm for the slotted-ALOHA system is also presented
