FIR channel-shortening equalizers for MIMO ISI channels

چکیده

Finite-length delay-optimized multi-input multi-output (MIMO) equalizers that optimally shorten the impulse response memory of frequency-selective MIMO channels are derived. The MIMO equalizers are designed to minimize the average energy of the error sequence between the equalized MIMO channel impulse response and an MIMO target impulse response (TIR) with shorter memory. Two criteria for optimizing the MIMO TIR are analyzed and compared. The presented analytical framework encompasses a multitude of previously-studied finite-length equalization techniques.

Stable and Causal Lti-precoders and Equalizers for Mimo-isi Channels with Optimal Robustness Properties

In this paper, we address the problems of precoding and equalization in frequency-selective MIMO channels by channel inversion. The channel is assumed to be stable and causal. As our main result, we give a closed form expression for a linear precoder which is stable and causal as well as timeinvariant. In particular, our solution further is optimal in terms of robustness and not restricted to f...

Design of FIR Precoders and Equalizers for Broadband MIMO Wireless Channels with Power Constraints

This paper examines the optimum design of FIR precoders or equalizers for multiple-input multiple-output (MIMO) frequencyselective wireless channels. For the case of a left-coprime FIR channel, which arises generically when the number nT of transmit antennas is larger than the number nR of receive antennas, the Bezout matrix identity can be employed to design an FIR MIMO precoder that equalizes...

Column-anchored zeroforcing blind equalization for multiuser wireless FIR channels

We propose a direct blind zeroforcing approach to cancel intersymbol interference (ISI) in multiple user finite impulse response (FIR) channels. By selectively anchoring columns of the channel convolution matrix, we present two columnanchored zeroforcing equalizers (CAZE), one without output delay and one with a chosen delay. Unlike many known blind identification algorithms, these equalizers d...

Blind Equalization for MIMO FIR Channel in Wireless Communication Systems

In wireless communication systems, equalization process is needed to suppress the inter-symbol interference (ISI) caused by multipath channels. Conventional equalization techniques use training signals. Blind Methods are of great importance in the digital signal communication systems as they allow channel equalization at the receiver without the use fof training signals. A blind equalization in...

n MIMO Systems in Rayleigh Channels with Maximum Likelihood Equalization Scheme

Channel equalizers are used to reduce the ISI arising from the delay spread or band limitation of the channel by adjusting the pulse shape so that it does not interfere with the neighbouring pulses. Equalization is a million intensive functions in cellular phone receivers. Channel equalization was first used in echo cancellation in telephone networks. The Maximum Likelihood equalizer achieves a...
