We investigate and evaluate the application of the soft information in the detection of cooperative spatial multiplexing (CSM) systems. The destination detects the signals transmitted from the relays with successive interference cancellation (SIC) whose performance suffers from the error propagation. The traditional detection methods assuming that the prior-detected symbols are correct, none of them...
In the conventional zero-forcing ordered successive interference cancellation (ZF-OSIC) or minimum mean square error ordered successive interference cancellation (MMSE-OSIC) detection algorithm of vertical Bell-Labs layered space-time (V-BLAST) architecture, there exists an undesirable processing delay due to the calculation of the matrix pseudo-inverse and power reordering in detecting the symbol...
Maximum-likelihood detection (MLD) can achieve optimum performance for the vertical Bell laboratories layered space-time (V-BLAST) architecture. However, due to its exponentially high computational complexity, several near-optimal detection algorithms, including some parallel detection (PD) ones with low complexity and high stability, have been proposed instead for practical systems. Nevertheless,...
The Vertical Bell Laboratories Layered Space-Time (V-BLAST) scheme achieves very high spectral efficiency while maintaining low implementation complexity. There have been great efforts focusing on the V-BLAST detection algorithms. However, all these algorithms concentrate on the symbol-wise detection. In this paper, a bit-wise V-BLAST detection algorithm is proposed based on the fact that the bits...
