We consider high speed packet data access service (HSDPA) which is introduced with the Release-5 of UMTSFDD standard. Signal to interference + noise ratio (SINK) and throughput bounds from the usage of channel matched filter (RAKE in FIR form) and LMMSE equalizer + correlator type mobile terminal receiver structures are obtained for the high speed downlink shared channels (HSDSCHs) under certain residual intracell interference levels which represent the situations after the possible usage of front end intracell interference cancellers. Exact orthogonality factor expression is obtained which is valid for any type of linear receiver. The distributions of radio channel parameters and received powers from the own and surrounding base stations are modeled under correlated shadowing w.r.t the mobile position, the cell radius and the type of environment. From such modeling, more realistic performance figures might be obtained as compared to fixing them to certain values. © 2005 IEEE.
