Abstract
Nowadays, wireless communication networks substantially increase the amount of information transmitted. Therefore, the development of novel technologies that supply this demand of the markets is necessary. In this context, Generalized Frequency Division Multiplexing (GFDM) is a solution for 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 the GFDM system. The BPSK, QPSK modulations, and matrix signal models 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 the BPSK modulation outperforms the QPSK modulation for all channels.
