Fast-convolution implementation of linear equalization based multiantenna detection schemes

This contribution addresses the channel equalization for MIMO systems utilizing filter bank based multicarrier (FBMC) transmission. The proposed frequency-domain MIMO equalizer is integrated with the subcarrier processing of the fast-convolution filter bank (FC-FB) structure. The performance of the proposed scheme is evaluated for both the static user and the user with high mobility in highly frequency-selective propagation scenarios. It is shown that integrating the equalization functions with the FC-FB processing leads to a highly efficient overall implementation.
