Analysis Study to Improve The Power Spectral Density of the GFDM Signal Using Windowing

Abstract

The application of windowing to Generalized Frequency Division Multiplexing GFDM signal is very fruitful in achieving significant damping of the level of Out Of Band (OOB) emission and thus reducing interference with surrounding devices, especially in next cellular generation applications.

In this paper, an analytical study of the windowing application process on the GFDM signal was presented, where the different types of time windows were studied, the mathematical function of each time window was clarified, and each function applied with the help of MATLAB software, and the results were extracted from the simulation process and discussed.
