mating jointly frequency offset and symbol timing of a linearly
modulated waveform transmitted through a frequency-fl at fading
channel. The methods exploit the received signal’s second-order
cyclostationarity and, with respect to existing solutions: 1) they
take into account the presence of time-selective fading effects 2)
they do not need training data 3) they do not rely on the Gaussian
assumption of the complex equivalent low-pass channel process
and 4) they are tolerant to additive stationary noise of any color
or distribution.
