PROJECT TITLE :

Lattice reduction aided tabu search with channel-dependent stopping criterion for MIMO systems

ABSTRACT:

An initial solution primarily based on lattice reduction (LR) and a novel stopping criterion for the tabu search (TS) detection algorithm are proposed to be used in multiple input multiple output (MIMO) antenna systems. LR aided-detection is performed and its result is utilised as an initial answer to the TS algorithm, whereas a measure of the condition of the lattice-reduced channel is used as a criterion for early termination of the algorithm. On the basis of the simulation results, this approach outperforms other initial solutions by regarding three.five dB at a BER of 10-3 for the 16-QAM sixteen × 16 MIMO with solely a slight increment in computational value. The proposed stopping criterion reduces the complexity further with nearly no loss in BER performance.
