英文摘要: Abstract(#br)The blind estimation of the symbol rate is one of the main issues for blind characterization of linearly modulated sequences. The estimator proposed in this article is based on the autocorrelation function of this kind of signal and exploits its limited frequency support.(#br)We prove theoretically that taking into account this property to modify some classical algorithms allows improving significantly their performances. We illustrate this result by numerical simulations, and we show that our estimator correctly detect the symbol rate in nearly 100% of the cases in many contexts as long as the signal to noise ratio is higher than 5dB.
