Deep learning-based DOA estimation for hybrid massive MIMO receive array with overlapped subarrays

Deep learning-based DOA estimation for hybrid massive MIMO receive array with overlapped subarrays

Abstract As massive MIMO is a key technology in the future sixth generation (6G), the large-scale antenna arrays are widely considered in direction-of-arrival (DOA) estimation for they can provide larger aperture and higher estimation resolution. However, the conventional fully digital architecture...
