Abstract
The preferred embodiments generalize the Band Edge Component Maximization (BECM) timing recovery method and provide blind timing recovery in Quadrature Amplitude Modulation (QAM) using all the available information rather than sampling the BECM output at the symbol rate.
Claims3
A timing recovery method, comprising the steps of:
- (a) sampling an input signal at a sample rate, said signal with quadrature amplitude modulation, said sampling at a rate higher than the symbol rate of said input signal;
- (b) filtering said sampled signal to yield a left band edge sampled signal and a right band edge sampled signal;
- (c) combining said left band edge signal and said right band edge signal to form a complex sampled signal;
- (d) controlling said sampling by said complex sampled signal.
