Abstract	In this paper, we show by simulations that the interference generated by the synchronization channel (SCH) and common pilot channel (CPICH) has considerable impact on the throughput of the high-speed physical downlink shared channel (HS-PDSCH) in UMTS. First, the simulation model for high speed downlink packet access (HSDPA) in UMTS is described. The downlink physical layer for the user data on the HS-PDSCH is modelled in detail, whereas the associated signalling is idealised as error-free. The interference from signalling and data channels on the HS-PDSCH is modelled adequately. As a general guideline for system settings in the simulations, we use the test cases specified in 3GPP TS 25.101 whenever applicable. Cancelling the SCH interference at the mobile side leads to an improvement of approx. 1 dB on an additive white Gaussian noise channel. Therefore, it is worthwhile to implement interference cancellation (IC) for the SCH and CPICH in future mobile receivers for HSDPA.
