One-snapshot on-grid and off-grid channel estimation in uplink large-scale millimeter-wave MIMO using an exponential penalty function

Large-scale multiple-input multiple-output (MIMO) technology is well-recognized for enhancing throughput in modern communication systems. In these systems, the accurate estimation of the direction of arrival (DoA) and uplink channel estimation is essential to leverage spatial multiplexing before the...
