1. A method, comprising: receiving, by a processor coupled to a plurality of sensors, at least a first noisy input signal and a second noisy input signal, each of the first noisy signal and the second noisy signal from the plurality of sensors; determining, by the processor, at least one estimated noise correlation statistic between the first input signal and the second input signal; and executing, by the processor, a learning algorithm in an adaptive blocking matrix that estimates an inter-sensor signal model between the first noisy input signal and the second noisy input signal based, at least in part, on the at least one estimated noise correlation statistic such that a noise correlation is maintained between an input to an adaptive noise canceller module and an output of the blocking matrix.
