An Iterative Method for Blind Equalization of Multiple FIR Channels
Fang‐Biau Ueng · IEICE Transactions on Communications · 2005
In this paper, the p erformance of the multiple-shift correlation (M SC) based blind channel equalizer (BCE) under channel order mismatch due to small head and tail channel coefficients is investigated.The analysis results show that the output signal-to-interference plus noise ratio (SINR) of the M SC-based BCE is degraded due to the sm all channel coe cients.The p erformance degradation is function of the optimal output SINR, the optim al output power, and the control vector.In such channel order m ismatch environm ent, this pap er proposes a sim ple but e ective iterative metho d to im prove the perform ance.Analysis of the iterative metho d is also perform ed.Simulation examples are demonstrated to show the e ectiveness of the proposed m ethod and the analyses.
