On the performance of open-loop transmit diversity techniques for IS-2000 systems a comparative study.

Third-generation code-division multiple access (CDMA) cellular systems incorporate a downlink transmission technique called transmit diversity (TD). This paper provides a comprehensive investigation of the performance and practical implementation issues of open-loop transmit diversity schemes for th...
