Abstract
Random access channel (RACH) is an uplink contention-based channel specified in wideband code-division multiple-access (WCDMA) wireless systems. Proposed is an analytical model for throughput evaluation of RACH operating in frequency division duplex (FDD) mode. The impacts of traffic arrival rate, available preamble signatures and message length on the performance are analysed. Simulations validate the high accuracy of the analytical model.
