Fast fading causes the loss in SE which is amplified by using multiple transmit antennas. The channel model considered here is block Rayleigh-fading Channels which resembles the practical scenario of cellular communication. Kronecker model is considered for modeling the spatially correlated channels. ...
multi-input multi-output (MIMO) Rayleigh fading channel. The proposed codes use single- input single-output (SISO) component codes based on algebraic number theory in the so called diagonal BLAST (D-BLAST) architecture. Based on a pairwise error probability ...

Rayleigh fading channel Abstract In this paper, in order to improve error correction capacity, the following method is proposed for constructing multilevel codes with interdependencies among the levels. First, one of the component codes of a basic multilevel code is divided into 2i (i = 1, 2...
systems on Rayleigh fading channels ire analyzed by the derived upper bounds of the BEM and computer simulation. Analyses show that the upper bounds derived are effective in evaluating the BER characteristics of the BCM systems when there are channel estimation cacti and the proposed BCM systems ...
Multi-input single-output (MISO) and multi-input multi-output (MIMO) channels are considered subject to block Rayleigh fading. Each coherence block contains $L$ symbols, and is spanned by $T$ training symbols, $B$ feedback bits, and the data symbols. The training symbols are used to ...
Three new Block Code Diversity combing schemes for digital transmission over a Rayleigh fading channel have been proposed. It has been shown that improved performance in term of probability of error versus signal to noise ratio has been obtained using soft-decision Viterbi decoding together with diver...
