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 3):
The sound processing node of  claim 2 , wherein the processor is configured to determine the plurality of weights using the transformed version of the robust linearly constrained minimum variance approach on the basis of the following equation and constraints: min . \ue89e \u2211 i \u2208 V \ue89e \u2211 l = 1 M \ue89e 1 2 \ue89e NM \ue89e t i ( l ) * \ue89e t i ( l ) + \u03b1 2 \ue89e w i H \ue89e w i \ue89e \n \ue89e s . t . \ue89e \u2211 i \u2208 V \ue89e D i ( p ) \ue89e H \ue89e w i = s ( p ) \ue89e \ue89e \u2200 p = 1 , \u2026 \ue89e P \ue89e \n \ue89e \ue89e \u2211 i \u2208 V \ue89e t i ( l ) = \u2211 i \u2208 V \ue89e NY i ( l ) \ue89e H \ue89e w i \ue89e \ue89e \u2200 l = 1 , \u2026 \ue89e M , wherein w i  denotes the i-th weight of the plurality of weights, Y i (l)  denotes the vector of sound signals received by i-th sound processing node, V denotes the set of all sound processing nodes, M denotes the total number of microphones of all sound processing nodes, i.e. M=\u03a3 i=1 N m i , N denotes the total number of sound processing nodes, D i (p)  defines a channel vector associated with a p-th direction, P denotes the total number of directions and s (p)  denotes the desired response for the p-th direction.
