Beam-forming for MC-CDMA systems
R. Venkatasubramanian, Jiann-An Tsai, Richard Michael Buehrer · 2003
In this paper, the use of adaptive antenna arrays for MC-CDMA systems in an interference-dominated environment is investigated. We present two different beam-forming approaches, namely, frequency domain and time domain beam-forming. Beam-forming performance over different channel conditions such as flat fading, frequency selective fading, low and high angle spreads and low and high Doppler spreads are studied.
