The authors propose a stochastic approximation algorithm for estimating multichannel coefficients. Convergence towards the true parameters is proved up to a scaling factor. The estimate is updated after receiving each new observation, so the output data need not be collected in advance. The input signal is allowed to be dependent, and the observation may be corrupted by noise. No noise statistics are used in the estimation algorithm.
