ABSTRACT:
A system includes an estimation module, a processing module, and a control module. The estimation module receives a signal having N sub-carriers and generates N first estimates for channel gains of the N sub-carriers, where N is an integer greater than 1. The processing module generates N second estimates based on the N first estimates. The control module generates N differences between each of the N first estimates and corresponding ones of the N second estimates and estimates (i) a channel gain of the signal and (ii) a preamble sequence in the signal based on the N differences.
