Space-Path Division Multiplexing Technique over Frequency Selective MIMO Channels

چکیده
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 mean square error (MMSE) turbo equalization technique is utilized to suppress inter and intra-mode interferences. The aim of the exploitation is to achieve performance robustness against spatial correlation. Computer simulation results confirm the effectiveness of the proposed technique. Keywords— MIMO, eigenmode transmission systems, soft interference canceling, MMSE filter, turbo equalization

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...

--A novel technique to enhance the robustness of space–frequency block coded (SFBC) orthogonal frequency-division multiplexing (OFDM) systems. The proposed system shapes the channel matrix of a frequency-selective fading channel into a piecewise flat--fading over each block of two adjacent subcarriers. Analytical and simulation results show that the proposed scheme substantially outperforms the...
متن کاملOn the design of space-time and space-frequency codes for MIMO frequency-selective fading channels
Recently, the authors introduced an algebraic design framework for space–time coding in flat-fading channels [1]–[4]. In this correspondence, we extend this framework to design algebraic codes for multiple-input multiple-output (MIMO) frequency-selective fading channels. The proposed codes strive to optimally exploit both the spatial and frequency diversity available in the channel. We consider...
متن کاملPseudo Eigenbeam-Space Division Multiplexing (PE-SDM) in Frequency-Selective MIMO Channels
In a frequency-selective multiple-input multiple-output (MIMO) channel, the optimum transmission is achieved by beamforming with eigenvectors obtained at each discrete frequency point, i.e., an extension of eigenbeam-space division multiplexing (E-SDM). However, the calculation load of eigenvalue decomposition at the transmitter increases in proportion to the number of frequency points. In addi...

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
