Abstract
A multiple-input multiple-output (MIMO) receiver comprises a MIMO frequency-domain equalizer, which comprises a MMSE filter for mitigating inter-symbol interference and an adder for mitigating inter-antenna interference, a MIMO detector and a MIMO decoder for processing a received MIMO signal and for estimating transmit bits. The receiver comprises a feedback path from the decoder to the detector for providing soft-information on the transmit bits to the detector and an additional feedback path from the decoder to the MIMO frequency-domain equalizer for providing soft-information to the MMSE filter and to the adder of the equalizer.
