description A device for Frame Synchronization and coarse frequency offset estimation (CFE) and a method thereof is provided. The method may include the step of receiving a communication signal in a matched filter. The matched filter may be configured for selecting one or more blocks from the communication signal. The matched filter may be further configured for filtering the blocks to obtain an output of the matched filter. The method may also include the step of providing the output of the matched filter to a frame synchronizer and to a coarse frequency estimator. The method may include the step of obtaining substantially simultaneously a symbol boundary using the frame synchronizer and a plurality of metrics using the coarse frequency estimator. Each of the metric may be an indicative of an estimate of coarse frequency offset. The method may further include a step of selecting one of the metric from the plurality of metrics according to the symbol boundary for obtaining an estimate of the coarse frequency offset. The method further provides a step of obtaining the estimate of the coarse frequency offset by performing an inverse tangent operation on the selected metric.
