Beamforming is a technique used to improve the signal-to-noise ratio of received signals, eliminate undesirable interference sources, and focus transmitted signals to specific locations. Beamforming is central to systems with sensor arrays, including MIMO wireless communications systems such as 5G, LTE, and WLAN.
The noise adaptive beamforming technology described herein attempts to minimize the adverse effects resulting from microphone hardware differences, dynamically changing noise sources microphone...

adaptive beamforming algorithms. But we are interested in localizing the sources, so for this, we implement DoA estimating algorithms that are mainly based on the specific properties of desired signal covariance matrix. Thus the observation space is subdivided into 2 spaces, one is signal space and other is noise space.
Adaptive Beamforming using MUSIC Pseudo-Spectrum Figure 1: Conventional beamformers can use an array of sensors to estimate DOA Estimation of Direction of Arrival (DOA) is a vital task in many practical applications such as smart antennas, high-resolution radar, underwater acoustics, noise reduction, to mention a few.
Adaptive beamformers provides superior interference rejection compared to that offered by conventional beamformers. When the knowledge about the target direction is not accurate, the LCMV beamformer is preferable because it prevents signal self-nulling.
