Precoded Orthogonal Space-Time Block Codes Over Correlated Ricean MIMO Channels
A precoder is designed for orthogonal space-time block codes (OSTBCs) for arbitrarily correlated Ricean multiple-input multiple-output (MIMO) channels. Unlike previous works, our precoder is the first to be designed to minimize the exact symbol error rate (SER) as function of both a) the joint transmit-receive channel correlation coefficients, and b) the MIMO Rice component, which are fed back ...
متن کاملDifferential space-time modulation with transmit-beamforming for correlated MIMO fading channels
While the knowledge of each channel realization is not available in a system with differential space-time modulation, channel correlation can be easily estimated without training at the receiver, and exploited by the transmitter to enhance the error probability performance. We develop a transmission scheme that combines transmit-beamforming with differential space-time modulation based on ortho...
متن کاملAnalysis of Differential Orthogonal Space-Time Block Codes over Semi-Identical MIMO Fading Channels
We study the performance of differential orthogonal space-time block codes (OSTBC) over independent and semi-identically distributed block Rayleigh fading channels. In this semi-identical fading model, the channel gains from different transmit antennas to a common receive antenna are identically distributed, but the gains associated with different receive antennas are non-identically distribute...
متن کاملCooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel
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...
متن کاملOn the Asymptotic Performance of Mimo Correlated Ricean Channels
In this paper we investigate the performance of block-fading Multiple Input Multiple Output (MIMO) Ricean correlated channels in the case where the number of transmit and receive antennas converge to infinity at the same rate. In this context we show that the expressions of classical performance indices such as the average mutual information or the output SINRs of MMSE receivers converge to det...
