Adaptive Step Size Gradient Ascent ICA Algorithm for Wireless MIMO Systems

Algorithm 2

The ASS-GAICA 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)	Calculate entropy of the mixed received data vectors as
(5)	Calculate matrix as follows:
(6)	Calculate matrix as
(7)	Update the unmixing matrix using the following equation:
(8)	Terminate the loop if
	, where is very small
(9)	end for
