Performance of wideband CDMA using space-time spreading over multipath Nakagami fading channels

چکیده
In this contribution the performance of wideband code-division multiple-access (W-CDMA) systems using spacetime spreading (STS) based transmit diversity is investigated, when frequency-selective Nakagami-m fading channels, multiuser interference and background noise are considered. The analysis and numerical results suggest that significant diversity gain can be achieved by employing several transmit antennas or/and by combining several multipath components. Furthermore, both the transmit diversity and the frequency-selective diversity appear to have the same order of importance.

A novel multiple access scheme based on slow frequency hopping multicarrier direct-sequence code division multiple access (SFH/MC DS-CDMA) is proposed and investigated, which can be rendered compatible with the existing second-generation narrowband CDMA and third-generation wideband CDMA systems. The frequency hopping patterns are controlled by a set of constant-weight codes. Consequently, mult...
