Suited architecture for massive MIMO detector based on antenna selection and LAS algorithm

Sequential likelihood ascent search detector for massive MIMO systems

“…In [17], an algorithm that uses multiple outputs is developed. Differently from [15], [16], [17], which consider some ways to improve the bit error rate (BER) performance based on the likelihood ascent search while increasing complexity, our approach reveals that there is an optimal value for the bit flip parameter. As a result, this approach improves the BER performance with a marginal complexity increase.…”

“…The LAS detection performance can be improved via optimization techniques, as in [15], where the antenna selection is made before the detector acts, aiming at maximizing the SNR and capacity. In [16], the search for the best solution is done in a non-fixed neighborhood.…”
