Abstract :
In this paper, an SNR based scheme is detailed for clock recovery in a multi-carrier communication system. This scheme shows an optimal way to combine a multitude of sub-carriers to arrive at a clock error estimate using individual tonal SNR and second order statistics of the additive noise to ensure a predefined confidence level for the residual clock error The scheme can be used even if the tones are modulated (by the transmitter) with a known or unknown (to the receiver) sequence of symbols (data)
