  • Abstract
    In this paper, blind and group-blind detectors are proposed based on the constant modulus (CM) property of the transmitted signals. By adopting blind and group-blind CM detectors, signi£cant gains are attained compared to the original blind and group-blind detectors, with only a slight increase in complexity. The SINR of the blind and group-blind CM detectors approach the theoretical upper bound for SINR (Cramer-Rao bound). Furthermore, the proposed detectors perform almost as well as the exact MMSE detector at high SNR.
