A Reduced-Rank 2-D Space-Frequency Receiver for MC-CDMA Systems with Multistage Wiener Filters
Yen‐Chen Chen · IEICE Transactions on Communications · 2005
In this letter, we propose a 2-D receiver structure for multicarrier code division multiple access (MC-CDMA) systems with the reduced-rank multistage Wiener filter. Due to the fast convergence property of the reduced-rank processing, it outperforms MMSE-based receivers with the classical Wiener solution, which is estimated by using a limited number of samples.
