| Abstract: | In wireless MIMO (multiple-input multiple-output) communication systems, the limit to channels can be further reduced by utilizing blind estimation methods based on higher-order statistics. This paper introduces the mathematical model of the blind FIR MIMO system and three typical blind channel estimation algorithms based on higher-order cumulant, then by analyzing and comparing, gives the simulation examples ,its drawbacks and something can be improved. |
