Classification Weighted Deep Neural Network Based Channel Equalization for Massive MIMO-OFDM Systems
Publikováno v:
Radioengineering, Vol 31, Iss 3, Pp 346-356 (2022)
Massive multi-input multi-output (MIMO) has attracted significant interest in academia and industry, which can efficiently increase the transmission rate. However, the error rate of conventional channel equalizations in massive MIMO systems may be hi
