The emerging massive/large-scale multiple-input multiple-output (LS-MIMO) systems that
rely on very large antenna arrays have become a hot topic of wireless communications …

Overcoming the conventional trade-off between throughput and bit error rate (BER)
performance, versus computational complexity is a long-term challenge for uplink Multiple …

We propose low-complexity detectors for large MIMO systems with BPSK or QAM
constellations. These detectors work at the bit level and consist of three stages. In the first …
