Abstract:
A sound processing node for an arrangement of sound processing nodes is disclosed. The sound processing nodes being configured to receive a plurality of sound signals, wherein the sound processing node comprises a processor configured to determine a beamforming signal on the basis of the plurality of sound signals weighted by a plurality of weights, wherein the processor is configured to determine the plurality of weights using a transformed version of a linearly constrained minimum variance approach, the transformed version of the linearly constrained minimum variance approach being obtained by applying a convex relaxation to the linearly constrained minimum variance approach.

Claim (Index 8):
The sound processing node of  claim 7 , wherein the processor is configured to determine the plurality of weights on the basis of a distributed algorithm by iteratively solving the following equations: \u03bb i , k + 1 = ( B i H \ue89e A i - 1 \ue89e B i + \u2211 j \u2208 \ue52d \ue8a0 ( i ) \ue89e R pij ) - 1 \ue89e ( C + \u2211 j \u2208 \ue52d \ue8a0 ( i ) \ue89e ( D ij \ue89e \u03d5 ji , k + R pij \ue89e \u03bb j , k ) ) \u03d5 ij , k + 1 = \u03d5 ji , k - R pij \ue8a0 ( D ij \ue89e \u03bb i , k + 1 + D ji \ue89e \u03bb j , k ) wherein (i) defines the set of sound processing nodes neighboring the i-th sound processing node and R pij  denotes a positive definite matrix that determines the convergence rate and that is defined \u2200(i, j)\u2208E by the following equation: R pij = 1 N \ue89e ( B i + B j ) H \ue89e A i - 1 \ue8a0 ( B i + B j ) .
