A Comparative Study of Equalization Techniques for MIMO Systems

چکیده
Multiple-input-multiple-output (MIMO) system has become one of the major focuses in the research community of wireless communication and information theory. Due to the channel characteristics, severe inter-symbol interference (ISI) may occur to the transmitted signals. Therefore it is necessary to use an equalizer to counter the effect of the channel. The effect of fading and interference effects can be combated with equalizer. In this paper, we propose different equalization scheme for MIMO systems such as, Zero Forcing (ZF) equalization, Minimum Mean Square Error (MMSE) equalization, Zero Forcing equalization with Successive Interference Cancellation (ZF-SIC), ZF-SIC with optimal ordering , MIMO with MMSE SIC and optimal ordering and ML.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Decision-feedback (DF) equalization schemes, wellknown from multi-user detection, offer the opportunity of an additional performance gain compared to their corresponding linear equalizers by feeding back past decisions on already detected symbols, based on a fixed symbol detection order. For MIMO systems, an optimum symbol stream detection order has been found within the VBLAST algorithm, which...

Multi-input multi-output (MIMO) technology is an emerging solution for high data rate wireless communications. We develop soft-decision based equalization techniques for frequency selective MIMO channels in the quest for low-complexity equalizers with BER performance competitive to that of ML sequence detection.
