Method and apparatus for equalization and data symbol detection for MPSK modulation |
摘要 |
A method and an apparatus for detecting data symbols of a multiple-phase-shift-keying (MPSK) modulated slot used for radio reception of digital data are disclosed. The method and apparatus simultaneously accomplish signal equalization and symbol detection. A simplified algorithm is used which is sub-optimal but closely approximates an optimal solution which significantly reduces computational load. A solution vector is constructed and data symbol values in the solution vector are perturbated. After each perturbation, a solution error is computed to determine whether the perturbated value provides a better solution. Perturbation continues until an optimal solution is found or a maximum number of iterations have been performed. The advantage is an improved, cost-effective radio receiver which enables faster wireless data transfer.
