OQAM implementation of GFDM

Generalised frequency division multiplexing (GFDM) is one of the promising contenders for fifth generation (5G) wireless communications. It is of great interest as it shows a number of advantages over cyclic prefix orthogonal FDM (CP-OFDM). However, the non-orthogonality scheme of GFDM introduces intersymbol and intercarrier interference (ISI/ICI). In order to mitigate these effects we explore the near orthogonality concept of offset quadrature qmplitude modulation (OQAM). A novel preliminary analysis of GFDM/OQAM is investigated in the presence of both Additive White Gaussian Noise (AWGN) and Rayleigh fading channels and it is seen that the symbol error rate (SER) performance, computed through simulations and analytical expressions, is improved.
