Abstract:

An algorithm based on higher-order cyclic cumulants for the estimation of SQAM and MQAM carrier frequency is proposed.The algorithm utilizes the cyclostationary property of communication signals and the higher-order cyclic cumulants of QAM signals.The theory of this algorithm is analyzed.The efficiency of the proposed estimation algorithm is verified via Matlab simulations.

Key words: carrier frequency estimation;higher-order cyclic cumulants;QAM
