1. A circuit for estimating symbol timing in one or more received data frames of a nominal constant envelope signal, the circuit comprising:
an envelope detector configured to generate an envelope detection output for the received data frames, the envelope detection output having an amplitude ripple associated with the symbol timing in the received data frames; and
a symbol timing estimator configured to receive the envelope detection output and generate a symbol timing estimation output based on the amplitude ripple.
