Abstract:- A blind adaptive multi-user detector for multi-carrier code-division multiple accesses (MC-CDMA) based on constant modulus algorithm (CMA) with an orthogonalized structures is proposed. The proposed system improves the performance of previously proposed blind MC-CDMA receiver by using a subband decomposition approach, in which the adaptation is carried out, independently, each band using the CMA to minimize a common error. Simulations shows that proposed approach reduce the computation cost while keeping a fairly good detection performance.
