Abstract
A timing recovery loop includes a sampler, a narrow band filter, an RMS normalize, a timing error detector, and a sample controller. The sampler samples a received signal. The narrow band filter filters the sampled received signal so as to pass an upper band edge of the received signal and not a lower band edge of the received signal. The RMS normalize sets an average power level of an output of the filter to a substantially constant value. The timing error detector detects a timing error with respect to an output of the RMS normalize. The sample controller controls the sampler in response to the detected timing error.
