Résumé:
With the increasing demand for mobile data traffic,
enhanced frequency localized transmissions are considered for
the generation of wireless networks to come. Filter Bank Multi-
Carrier modulation, with the use of Offset-QAM, proves to be
an interesting candidate to satisfy those spectrum constraints.
Contrary to CP-OFDM, FBMC does not use any CP. Its spectral
efficiency is improved but it also weakens the transmissions
over highly frequency selective channels. Complex detection stage
based on precoding or multi-tap equalization is thus necessary to
prevent orthogonality losses. Another solution can be the use of
the Frequency-Spreading scheme which improves the frequency
resolution. In this paper, we propose to extend probabilistic
decoding to linear FBMC receivers. The performances of the
two common FBMC receiver structures, PolyPhase Network and
Frequency-Spreading, are assessed over frequency-selective LTE
channel models. The Likelihood Metrics analytical formulae are
also derived.
