Abstract :
In this paper we show that the widely used blind adaptive minimum output energy algorithm fails to converge to the desired solutions when complex valued IIR equalization structure is used for digital VSB signals. We present analytic counter example for a simplified two tap channel case showing ill convergence of MOE algorithm.
