In this paper, a compressed sensing based method for beamforming from a single snapshot of an acoustic array is proposed. Firstly, the observation model is presented and then the problem of direction of arrival of acoustic sources estimation is expressed as an optimization problem constrained by signal sparsity. Then a modified orthogonal matching pursuit algorithm is provided to solve this problem...
Beamforming has been used in wireless sensor networks (WSNs) to increase the communication range of sensor nodes. These works investigate the beamforming performance using the theory of random arrays, and aims to achieve maximum transmitting power. Since the relative positions of sensor nodes and frequency/spatial response are generally unknown, it's also referred to as blind beamforming. In this...
