The paper presents the studies on the application of two scrambling codes for the data and control channels in HSUPA, aiming at increasing the uplink data rates. Appropriate physical channels power offsets selection and equalization can result in a link throughput gain of up to 28% as compared with the standard HSUPA transmission. Intensive HSUPA link level simulations have been performed to investigate optimization of the ratios of traffic to pilot channel powers and to measure parameters of the transmitted signal such as the peak-to-average power ratio and the cubic metric. The selected simulation results are presented in this paper. Index Terms — scrambling codes, HSUPA, link level simulation.
