Linear Filter Design for FBMC-OQAM Transceiver

The filter bank multicarrier offset-QAM transceiver is increasingly investigated for its use in multiple-access uplink scenario. The use of the filter bank multicarrier transceiver, however, is attractive when a simple equalizer with a few taps is able to perform correct equalization. In this paper it is provided an extension of a general matrix description of the considered transceiver that is much useful for correctly setting the overall number of subcarriers for which simple channel equalization is possible. The obtained frequency-domain description allows the derivation of a class of simple receiver equalizers; two examples of possible equalizer derivations are provided.
