Performance of Adaptive Array Antenna for Multicarrier CDMA System in Slow Nakagami-m Fading Channels
Ze-Guang Jin, Heau-Jo Kang, Yoon-Ho Kim · 2007
In this paper, we analysis the multicarrier code-division multiple-acess(MC-CDMA) based on a fractionally spreading, ie. FS MC-CDMA system, reduction of inter-symbol interference is an important problem. This paper proposes an adaptive array antenna system, which can improve performance by a cmbination of temproal and spatial filtering. While the adaptive array suppresses interference sources with arrival angles different from that of the desired user. The proposed system can achieve stable acquisition and low error rate of demodulated data even in a heavy interference channel.
