“…To deal with the multi-DOA estimation problem, we also use the PLS to decrease the scale of dataset space and obtain multiclassification results with high performance. We denote the training data as D = R (1) , z z z (1) , R (2) , z z z (2)…”

“…It is generally known that the performance of parameter detection highly depends on the accurate determination of the number of target signals [4]. Through an extensive literature study and survey, we find that the commonly used methods for detection of the number of target signals are the Minimum Description Length (MDL) [5], Akaike Information Criterion (AIC) [6], and Gerschgorin Disk Estimator (GDE) [7]. However, these methods perform poorly under some non-ideal conditions (say, low Signal-to-Noise Ratio (SNR) and small snapshots).…”

“…Base stations rely on massive MIMO systems to uplink sounding signals, and compute channel knowledge to enable MIMO beam-forming [ 14 , 15 , 16 ]. Therefore, direction-of-arrival (DOA) estimation is important for massive MIMO], as it is needed to complete the predicted capacity gains [ 17 , 18 ]. Various DOA estimation algorithms have been proposed in recent years, such as improved multiple signal classification (MUSIC) [ 19 ], estimation of signal parameters via rotational invariance techniques (ESPRIT) [ 20 ], and the propagator method (PM) [ 21 ].…”
