  • Abstract
    A constrained constant modulus approach (CMA) for blind multiuser detection is investigated. In the noiseless case, the sufficient and necessary conditions under which the constrained CMA can completely remove multiaccess interference (MAI) are derived. According to the conditions a non-canonical constraint must be considered to strengthen the ability of CMA to suppress MAI. The simulation examples demonstrate the results
