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 [5] whenever applicable.
Cancelling the SCH interference at the mobile side leads
to an improvement of approx. 1dB 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.
