Gradient ascent ICA algorithm.

(1)	Initialization
	Whiten the mixed received data
	Choose a random initial unmixing matrix
	Select the number of maximum iterations
(2)	for to do
(3)
(4)	Update the unmixing matrix using the following equation:
(5)	Terminate the loop if
	, where is very small
(6)	end for
