Low-Complexity Channel Estimation in 5G Massive MIMO-OFDM Systems

Low-Complexity Channel Estimation in 5G Massive MIMO-OFDM Systems

Pilot contamination is the reuse of pilot signals, which is a bottleneck in massive multi-input multi-output (MIMO) systems as it varies directly with the numerous antennas, which are utilized by massive MIMO. This adversely impacts the channel state information (CSI) due to too large pilot overhead...
