Title: Handoff issues in a transmit diversity system
Author: Jaswal, Kavita
Abstract: This thesis addresses hando ? issues in a WCDMA system with space -time block coded transmit antenna diversity . Soft hando ? has traditionally been used in CDMA systems because of its ability to provide an improved link performance due to the inherent macro diversity . Next generation systems will incorporate transmit diversity schemes employing several transmit antennas at the base station . These schemes have been shown to improve downlink transmission performance especially capacity and quality . This research investigates the possibility that the diversity obtained through soft hando ? can be compensated for by the diversity obtained in a transmit diversity system with hard hando ? . We analyze the system for two performance measures , namely , the probability of bit error and the outage probability , in order to determine whether the improvement in link performance , as a result of transmit diversity in a system with hard hando ?s obviates the need for soft hando ?s .
