Estimation of a Time, Phase and Frequency Shift of an OQAM Multicarrier Signal

A device for receiving an OQAM type multicarrier signal comprising:

• means for estimating, in the time domain, at least one timing, phase and/or frequency shift of said multicarrier signal,
• said means for estimating comprising at least one estimator for estimation of the time shift, called a time estimator, and/or at least one estimator for estimating the phase shift, called a phase estimator, and/or at least one estimator for estimating the frequency shift, called a frequency estimator,
• wherein at least one of said estimators takes account of efficiency of a prototype filter used at transmission to shape at least one preamble in said multicarrier signal.

A non-transitory computer readable medium comprising a computer program stored thereon and comprising instructions for implementing a method for receiving an OQAM type multicarrier signal when the program is executed by a processor, wherein the method comprises:

• estimating by a receiver device, in the time domain, at least one time, phase and/or frequency shift of said multicarrier signal,
• said estimating implementing at least one estimator configured to estimate said time shift, called a time estimator, and/or at least one estimator configured to estimate said phase shift, called a phase estimator, and/or at least one estimator configured to estimate said frequency shift, called a frequency estimator,
• wherein at least one of said estimators takes account of coefficients of a prototype filter used at transmission to shape at least one preamble inserted into said multicarrier signal.
