Dual-mode algorithm for blind equalization based on second and fourth order cumulants
Yingmin Wang · Shengxue jishu · 2006
This paper considers the general blind equalization problem of non-minimum systems.A normalized cumulant consisting of second and fourth cumulants is proposed,and a blind equalization criterion for normalized cumulant matching presented.A new HOS algorithm is then derived,and an improved algorithm(dual-mode algorithm) proposed.Computer simulation results are included to compare the performance of the proposed algorithm.
