Performance of Wideband CDMA Using Adaptive Space-Time Spreading over Multipath Nakagami Fading Channels

Yang, L.L. and Hanzo, L. (2002) Performance of Wideband CDMA Using Adaptive Space-Time Spreading over Multipath Nakagami Fading Channels At VTC'2002, (Spring), United States. 06 - 09 May 2002. , pp. 615-619.

In this contribution an adaptive space-time spreading (ASTS) assisted transmit diversity scheme is proposed for improving the throughput of wideband code-division multiple-access (W-CDMA) systems. The performance of the system is investigated, when frequency-selective Nakagami-$m$ fading channels, multiuser interference and background noise are considered. Our numerical results demonstrate that the proposed ASTS-based transmission scheme is capable of significantly improving the effective throughput of W-CDMA systems. Specifically, the studied W-CDMA system’s bitrate can be increased by a factor of three at the modest cost of requiring an extra 0.4dB or 1.2dB transmitted power in the context of the investigated urban or suburban areas, respectively.
