Abstract

The random access channel (RACH) in UTRA-TDD is defined as an uplink contention-based transport channel that is mainly used to carry control information from mobile stations to base stations. We study the throughput performance of RACH on an additive white Gaussian noise (AWGN) channel whereby successful transmission of a burst requires the spreading code chosen to be collision-free and the burst error-free after convolutional decoding. Based on this model, the code-collision probability, the data bit error probability and the RACH channel capacity are derived. For spreading factor Q equal to 8 or 16 as specified in the standard, the maximum throughput obtained is 1.74 and 3.67, respectively
