The five noted methods, namely, complex acoustic intensity measurement (CAIM) method, weighted complex acoustic intensity measurement (WCAIM) method, conventional beamforming (CBF) method, minimum variance distortionless response (MVDR) beamforming method, and multiple signal characteristic (MUSIC) method, are investigated in this paper.
The above equation is known as MVDR. The optimal solution of (5) can be easily found, [w.sub.opt] = [beta][[??].sup.-1][a.sub.s], where [beta] = ([a.sup.H.sub.s][[??].sup.-1][a.sub.s]) 1 is a constant and it has no influence on the SINR.
One of the beamforming algorithm used in smart antenna is MVDR beamforming, which can calculate the weight vector to determine the desired signal from the interference.
Bayesian beamformer [9] is the sum of the MVDR beamformers (Equation (6)) along the interval of uncertainty weighted by the a posteriori pdf.

The beamforming algorithms are classified mainly into three types: (1) estimating the Angle Of Arrival (AOA) algorithms like MUSIC and ESPRIT [9,11-13], (2) non-blind algorithms where the transmitter and the receiver agree to certain code to detect the location of the transmitter to steer the main beam like Maximum Likelihood (ML), and Minimum Variance Distortionless Response (MVDR) [7], (3) blind beamforming algorithm.
In section 3, the problem formulation using the MVDR method is outlined.
Adaptive beamforming and high resolution direction-of-arrival (DOA) estimation algorithms have received much attention in the past a few decades, and among which, the minimum variance distortionless response (MVDR) [1] and multiple signal classification (MUSIC) algorithm [2] are the most popular two techniques.

One of the most commonly used adaptive beamformers is the minimum variance distortionless response (MVDR) algorithm.
MVDR (Minimum Variance Distortionless Response) is a typical beamforming (beamformer) algorithm, which was proposed by Capon in 1967 [3].
The beam-forming algorithms such as MVDR [3] and MEM 4] obtain a nonparametric spatial spectrum by optimizing the filter weights.
