Compilation of the different MATLAB codes that were used for the experimental part of the research work presented in the article "Next Generation 5G OFDM-Based Modulations for Intensity Modulation-Direct Detection (IM-DD) Optical Fronthauling".

Next Generation 5G OFDM-Based Modulations (OFDM, FBMC, GFDM, and UFMC):

Introduction

This MATLAB source code provides an implementation along with examples of a the diferent modulations candidate to substitute OFDM in the next generation of cellular systems 5G. I am sharing them with the idea of letting other members in the research community, who are working on the same or similar fields, to take advantage of our efforts and be able to repeat and improve our same experiments in their respective labs.

What is in this repo?

It contains both transmitter and receiver ends for OOK, OFDM, FBMC, GFDM, and UFMC multicarrier modulations. They are standalone and can be adapted for all types of simulation.

Note on licenses

These codes have been built during the Introduction to Research Program from Universitat Politècnica de Catalunya, while working under the Optical Communications Lab.

I am only responsible for the adaptations performed. Licenses from the original sources cited below should be taken into consideration.

OFDM, FBMC and UFMC codes have been created departing from the examples provided by 
Mathworks, available to the public in the following links: 

https://es.mathworks.com/help/comm/examples/fbmc-vs-ofdm-modulation.html
https://es.mathworks.com/help/comm/examples/ufmc-vs-ofdm-modulation.html

GFDM codes are just an adaptation of the 5GNOW test vector provided by
Vodafone chair/TU Dresden in: http://5gnow.eu/?page_id=427
They are not standalone. Notice that for them to work properly, the GFDM library 
available on the link above should be included in the project before execution.

Note: I have received messages saying that the 5gnow link seems to be down.
