Control Effort Strategies for Acoustically Coupled Distributed Acoustic Nodes

Algorithm 2

1r rescaling l-DMEFxLMS algorithm for -nodes WASN.

(1) for all    do

(2)     % Obtain local coefficients to generate the output signal

(3)     % Provisional output signal

(4) for all    do

(5)     % Vector that contains reference signal filtered by estimated acoustic channels

(6) end for

(7)     % Update local state

(8) if     % If provisional output signal is greater than threshold

(9)     % Rescale provisional output signal

(10)     % Rescale its portion within its local state

(11)     % Updated local state with rescaled coefficients

(12) end if

(13)     % Generate output signal

(14) end for
