Evaluation and Use of Interference Matrix for FBMC-OQAM Transceiver

The FBMC-OQAM transceiver is increasingly investigated for its use as alternative to OFDM transceiver. A general matrix description of the transceiver is able to describe the existing interferences among different transmitted symbols, and is often employed to design the prototype filter and the basic equalizer parameters. In the present paper the general model of FBMC-OQAM transceiver, already proposed by the authors and used for single-tap equalization, is considered and a method for its fast evaluation is proposed. Some applications of the proposed procedure to single-tap transceiver equalization are suggested; computer simulations are carried out in order to confirm the value of the proposed method.
