Abstract :
A new blind channel estimator for multi-carrier PSK transmission is developed. By exploiting the structure of PSK signals, the proposed channel estimator can identify non-minumum phase channel using only the power spectrum of received signals. Unlike existing subspace-based channel estimators, our scheme is based on symbol-block-by-symbol-block approach, and, thus, the channel tracking ability is improved. Simulation results demonstrate that the proposed blind receiver exhibits satisfactory performance.
