Abstract
A method of estimating coarse frequency offset of received symbols based on a received frequency domain sample at a ksub-carrier of a 53Orthogonal Frequency Division Multiplexing (OFDM) data symbol in a jtime slot (TS) of a receiver in aChina Multimedia Mobile Broadcasting (CMMB) mobile televisioncommunicationnetwork includes dividing a received sample, Y, into two sets of noise only tones and data plus noise tones D, obtaining a received sample only if there is a coarse frequency offset mismatch between a transmitter and the receiver, dividing a summation of a power of the data plus noise tones by a summation of a power of the noise only tones to obtain Λ, and estimating an integer coarse frequency offset estimate, Δ{circumflex over (f)}, of the received symbols when the Λis a maximum.
