Abstract :
We examine site selection diversity transmission (SSDT) for 3GPP WCDMA forward link by means of analytical tools. Hard handover (HHO), soft handover (SHO) and SSDT are compared by using the receiver bit error probability as a performance measure taking into account the effect of feedback bit errors as well as the shadow fading. Results show that without fast transmission power control the performance gain from SSDT can be seriously degraded by feedback bit errors.
