The ping\u2010pong optimized pulse shaping (POPS) paradigm was proposed as a powerful technique to generate a family of waveforms, ensuring an optimal signal to interference plus noise ratio (SINR) at the receiver. In this paper, we derive, for the first time, the analytical expression of the SINR for FBMC\/OQAM systems. We then adopt the POPS algorithm in the design of optimum transmit and receive waveforms for FBMC\/OQAM, with respect to the SINR criterion. For relatively high dispersions, numerical results show that the optimized waveforms provide a gain of 7\u2009dB, in terms of SINR, compared to the PHYDYAS waveform. They also show that the obtained waveforms offer better out\u2010of\u2010band (OOB) emissions with regard to those of the IOTA waveform. Furthermore, we notice that FBMC\/OQAM systems present a gain of 4\u2009dB in SINR, compared to FBMC\/QAM systems, when both operate at their time\u2010frequency lattice critical densities. However, FBMC\/QAM systems can guarantee, with a reduced computational complexity, a comparable performance to FBMC\/OQAM systems, in terms of SINR, when their spectral efficiency is relatively reduced by less than 5%.<\/jats:p>","DOI":"10.1155\/2018\/4637181","type":"journal-article","created":{"date-parts":[[2018,4,10]],"date-time":"2018-04-10T23:35:34Z","timestamp":1523403334000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["How Much FBMC\/OQAM Is Better than FBMC\/QAM?
