In this paper we introduce an adapted Constant Modulus Algorithm in order to identify the impulse response of an unknown propagation channel. This algorithm deals with the output of a fourth order moment estimation algorithm of received samples . This paper can be view as a follow up of a previous work devoted on blind channel estimation . It will be shown how results obtained in this previous work can be used as an initialization of the proposed adapted CMA leading to a subsequent improvement.
