Soft values based detector for bit interleaved coded modulation multi input multi output systems

With the advantages of spatial multiplexing multi input output (MIMO) systems in terms high transmission capacity, complexity detector at receiver side such is a major issue. Performance, bit error rate (BER) studied for interleaved coded modulation (BICM) MIMO systems. List based generation (bits) soft values considered 2 by 2, 4 with 16,64 quadrature amplitude (QAM) and different list sizes utilizing non systematic convolutional code. Using sphere partial tree search, scheme suggested shown to be more computationally efficient (in average number scanned nodes) than reported alternative block, flat fading channels. Simulation results reveal that performance BER can still maintained.
