Generalized Frequency Division Multiplexing (GFDM) is a promising multi-carrier modulation scheme for next-generation wireless communication systems. GFDM uses a non-orthogonal pulse shape, which leads to self-interference among sub-carriers. In this paper, we propose a new coded GFDM method to reduce the self-interference in each block by using a space-frequency block coding (SFBC) scheme. To this end, we introduce corrective coefficients based on channel state information and the demodulation matrix for each modulated data. We evaluate the bit error rate (BER) performance of the system by comparing SFBC-GFDM transmission in Rayleigh channels with a matched filter (MF) receiver. Our computer simulations show that the proposed scheme substantially improves the system performance in BER. Per our results presented in this paper, we achieve 5 dB performance improvement at BER of 10-2 compared to previous counterparts.
