Large-scale MIMO systems are well known for their advantages in communications, but they also have the potential for providing very accurate localization, thanks to their high angular resolution. A difficult problem arising indoors and outdoors is localizing users over multipath channels. Localization based on angle of arrival (AOA) generally involves a two-step procedure, where signals are first...
This paper concerns the direction of arrival (DOA)estimation for code division multiple access (CDMA) frequency on-selective and slow fading multipath and multi input multioutput (MIMO) channels. Through decorrelating processing we can employ one-dimensional unitary TLS-ESPRIT algorithm twice to solve the problem. Simulation results are presented efficient estimator.
