Abstract :
A new form of transmit diversity has been developed and included for Interim Standard 2000 (IS-2000) the third generation successor for IS-95 code division multiple access (CDMA) systems. This transmit diversity scheme which was developed by Bell Laboratories is similar in principle to space-time block coding methods developed for UMTS systems by Texas Instruments and by Tarokh et al.(see IEEE Transactions on Information Theory, vol.45, p.1456-67, 1999) for TDMA systems. This paper presents performance results of this new transmit diversity method, termed space-time spreading.
