A 2D Space-frequency Receiver with Reduced-Rank Multistage Wiener Filters for MC-CDMA Systems
Yung‐Fang Chen, Chung-Hung Wang · 2005
We propose a 2D receiver structure for MC-CDMA systems with a reduced-rank multistage Wiener filter, where the proposed 2D receiver does not require angle of arrival estimation and explicit channel estimation. Due to the faster convergence property of reduced-rank processing, it outperforms MMSE-based receivers with the classical Wiener solution estimated by using a small finite number of samples.
