Abstract

This paper proposes a blind carrier frequency offset (CFO) estimation for multi-carrier code-division multiple access systems over multipath fading channels. The scheme first determines a preliminary CFO estimate by maximizing the total output power of a set of correlators, which is constructed with the linearly constrained minimum variance optimization. A fine CFO estimate is subsequently found by solving the well-developed quadratic cost function. Finally, by using the frequency-compensated data, a subspace minimum output energy (MOE) receiver is formed to provide the maximum output signal-to-interference-plus-noise ratio. Numerical results demonstrate that, with the proposed CFO estimation as a stage proceed, the subspace MOE receiver can achieve nearly the performance of the optimal minimum mean square error receiver.
