GFDM/OQAM performance analysis under Nakagami fading channels

Abstract A lot of attention has been given recently to future multicarrier (MC) modulation techniques, for high speed robust wireless systems, in order to serve upcoming envisioned needs. Generalized Frequency Division Multiplexing (GFDM), a candidate for 5G, is a non-orthogonal modulation technique, proposed as an alternative to Orthogonal Frequency Division Multiplexing (OFDM) for future wireless communication systems. However, due to its non-orthogonal nature, GFDM introduces intersymbol and intercarrier interference (ISI/ICI). To mitigate these effects and to improve Symbol Error Rate (SER) system performance we explored the near orthogonality concept based on Offset Quadrature Amplitude Modulation (OQAM) and made the adaptation to the conventional GFDM system model. In this paper, we investigate SER performance under the Nakagami- m and Nakagami- q (Hoyt) fading channels. Analytical expressions for this SER performance are derived and the obtained results match those of the simulations that were carried out and confirms the effectiveness of the proposed GFDM/OQAM model to that of conventional GFDM.
