Turbo Equalisation for MIMO-OFDM Transmission with Insufficient Guard Interval
In this paper, we propose a novel frequency domain turbo equaliser for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) transmission in channels where the maximum excess delay exceeds the length of the guard interval. The turbo equaliser is based on minimum mean square error filtering and utilizes the soft feedback from channel decoding for the joint separation of the spatially multiplexed streams and cancellation of intersymbol interference (ISI) and intercarrier interference (ICI). To reduce complexity, only significant ISI/ICI terms are taken into account for signal detection, while the remaining terms are regarded as noise. Simulation results reveal that the proposed receiver shows a good compromise between complexity and performance
