Abstract :
We propose a 2D receiver structure for MC-CDMA systems with a reduced-rank multistage Weiner filter. The 2D space-frequency receiver does not require angle of arrival estimation and explicit channel estimation. Due to the faster convergence property of the reduced-rank processing, it outperforms MMSE-based receivers with the classical Weiner solution estimated by using a small finite number of samples.
