Abstract

We propose two novel frequency-domain equalization (FDE) architectures to combat wireless MIMO frequency selective channels. The first architecture combines the conventional FDE with time-domain decision feedback (FD-DFE), and the second architecture combines FDE with parallel interference cancellation (FDE-PIC). It is shown that both the structures significantly outperform the conventional MIMO FDE, OFDM and time-domain DFE structures, especially at a higher RMS delay spread.
