Abstract :
This paper considers the optimal equalization for FIR channels with random uncertainty arising from wireless communications. We shall first present a result that quantifies the mean H2 norm of random FIR channels in terms of linear matrix inequalities. The result allows us to solve the optimal H2 equalization problem via convex optimization. Simulations are carried out for both the real and complex channels and the results demonstrate the effectiveness of the proposed equalization technique
