The paper considers an important variation of the MIMO channel Decision Feedback (DF) equalizer, the bidirectional MIMO equalizer, that combines the classical forward DF equalizer (DFE) with the backward DFE, which is based on imposing anticausal properties to the feedback filter. With reference to the minimum mean square error (MMSE) cri- terion, we extend the bidirectional equalization from the single-input single-output (SISO) scenario to the more gen- eral multiple-input multiple-output (MIMO) scenario where different definitions of anticausal systems can be given. An original variation of the bidirectional DF equalizer is also proposed in order to reduce its performance loss in the pres- ence of the error propagation. ward DFE is designed by imposing that the feedback filter is causal. Since the definitions of causal and anticausal fil- ter admit several variations in the MIMO scenario, a detailed analysis is required to provide its extension to the MIMO scenario. In this paper we derive the MIMO bidirectional DF equalizer (Bi-DFE) according to the MMSE criterion and we analyze its performances in the presence of error propaga- tion. Moreover, in order to improve them, an original two- stage variation of such an equalizer is proposed. |
