Abstract :
The high speed downlink packet access (HSDPA) system has been investigated for adaptation in the GEO satellite environment in order to achieve high packet user throughput and system efficiency. This paper discusses the performance of the so called satellite-HSDPA (S-HSDPA) system, where the impacts of the power amplifier non-linearity, space time transmit diversity (STTD) and multicode transmission, are examined. The S-HSDPA performance is obtained from simulations of a modified terrestrial HSDPA link simulator in a rich multipath urban environment with three intermediate module repeaters (IMR). The results indicate an appropriate choice of system parameters.
