چکیده

In multi-antenna system, the correlations between the receiver antennas degrades the systems performance. In this paper, we propose a spatial decorrelation receiving technique in frequency-selective SIMO channels. A spatial-to-modal matrix is placed after the SIMO channel output to remove the correlations between the receiver antennas caused by the limited antenna separations. Simulation results of this newly proposed spatial decorrelation design demonstrate favourable BER improvement and better system performance.

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...

Identification of Unknown Uncorrelated Colored Signals Distorted by Unknown Convolutive Channels

A fundamental problem in adaptive sensor array processing is to identify unknown uncorrelated colored signals that are distorted by unknown convolutive channels. This problem is also known as blind identification of MIMO (multi-input-multioutput) systems. In this paper, we present a novel approach called BIDS (blind identification by decorrelating subchannels). The BIDS can identify an FIR (fin...

Frequency-Shift Zero-Forcing Time-Varying Equalization for Doubly Selective SIMO Channels

This paper deals with the problem of designing linear time-varying (LTV) finite-impulse response zero-forcing (ZF) equalizers for timeand frequency-selective (so-called doubly selective) single-input multiple-output (SIMO) channels. Specifically, relying on a basis expansion model (BEM) of the rapidly time-varying channel impulse response, we derive the canonical frequency-domain representation...

Space-Path Division Multiplexing Technique over Frequency Selective MIMO Channels

This paper proposes a new multiple-input multiple-output (MIMO) eigenmode transmission technique in frequency selective multipath channels. The proposed scheme exploits the two-dimensioned (spatial and path domain) signal separability in frequemcy selective MIMO channels, for which different data streams are transmitted on each path component’s eigenmodes. A soft interference canceling minimum ...
