FBMC RECEIVER USING A METHOD FOR SYNCHRONIZATION IN A FREQUENCY DOMAIN

摘要

A filter bank multi-carrier (FBMC) receiver implementing a synchronization in the frequency domain. The receiver includes a synchronization module including an error estimator on the sampling instants and, for each subcarrier, an interpolating filter for reconstructing the samples at the accurate sampling instants. A phase-shifter is provided, for each subcarrier, at the output of the interpolating filter, to make a phase compensation. The phase-shifter can be followed by an equalizer in the frequency domain.

1. A multi-carrier signal receiver synthesized by a synthesis filter bank, said receiver comprising a plurality of analysis filters for analysing said signal, after sampling, at sampling instants, the outputs of the filters being connected to a Fourier transform module providing, for a plurality of subcarriers, samples in the frequency domain, characterised in that it further comprises:
an error estimation module on the sampling instants (621), receiving said samples for at least one subset of said plurality of subcarriers and for a plurality of said sampling instants, and providing an estimation of said error; and, for each subcarrier of said plurality of subcarriers: an interpolating filter (622), receiving the estimation of said error and interpolating samples of a subcarrier to provide an interpolated sample at an error-corrected sampling instant.
