PENA, Randy Verdecia. Performance analysis of BPSK and QPSK modulation schemes for different channels conditions in GFDM system. Maskay [online]. 2018, vol.8, n.1, pp.7-12. ISSN 1390-6712.  https://doi.org/10.24133/maskay.v8i1.506.

Nowadays, the wireless communication networks are substantially increasing the number of transmission information. Therefore, the development of novel technologies that supplies this demand of the markets is necessary. In this context, Generalized Frequency Division Multiplexing (GFDM) arises as a solution for the future wireless communication networks. The principal goal of this research is to analyze the performance of Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) modulations for different conditions of the communication channel in GFDM system. The BPSK, QPSK modulations and matrix signal model of the GFDM system are presented. The performance is evaluated in terms of Bit Error Rate (BER) and three different channels are implemented: ideal, fixed, and fixed-random. The detection simulation results depict the performance curves for different scenarios and modulations. It can be noticed that for all channels the BPSK modulation outperforms the QPSK modulation.
