Abstract
A receiver in a communication system is provided that includes a synchronization module and a channel estimator. The synchronization module is configured to identify an end of a cyclic prefix (CP) in a received signal using slope detection by monitoring a detection metric threshold in the received signal. The channel estimator is configured to estimate a complex noise variance using guard band subcarriers.
