Subcarrier Power modulation based OFDM (OFDM-SPM) for future 6G and Beyond Network

Welcome to our course on OFDM-SPM (orthogonal frequency division multiplexing with subcarrier power modulation), a novel OFDM modulation technique for future wireless communication systems. In this course, you will be introduced to orthogonal frequency-division multiplexing with SPM and guided through its inner workings by your instructor Abdulwahab Hajar, co-author of a number of articles that brought OFDM-SPM into the telecommunication systems literature.

OFDM-SPM

The course will introduce orthogonal frequency-division multiplexing with SPM, explain why it is needed, clearly describe the working concept, go over the design specifics in terms of transmission and reception (modulation and demodulation) in detail, showcase the gains which orthogonal frequency-division multiplexing with SPM achieves over its counterparts and conventional OFDM modulation, present the simulation results of this scheme and translate them to performance measures, and last but not least, provide the viewer with ideas about how OFDM-SPM can be improved.

The course will equip the student with the following:

  • – An intuitive and strong understanding of OFDM-SPM, its working concepts, transceiver structure, its specifics and constraints in both the modulation and demodulation stages, and furthermore, the benefits and gains to using OFDM-SPM.
  • – A touch of novelty, as the course brings forth to the student, a novel modulation scheme, which by adding an extra data carrying dimension to a pre-existing technology was able to obtain great gains.
  • – Some insight into simulation results, and how these ultimately signify the performance of modulation schemes.
  • – An understanding of what is needed in state of the art, modern day modulation schemes.
  • – The motivation and ideas to continue with further research on this topic, especially since the code can be purchased from researcher store. This gives the student the opportunity to see what’s happening behind the scenes, and modify ODFM-SPM to perhaps attain better results.

Working Concept and Structure: Where All the Magic Happens!
In this lesson, we will cover the working concept of OFDM-SPM and its design specifics, through this all, we will: - Take a look at the transceiver structure of OFDM-SPM, and how it differs from that of conventional OFDM. - Explain how modulation and demodulation is done by means of subcarrier power modulation. - Go over an example, which shows the gains and advantages to using OFDM-SPM, when compared with conventional OFDM modulation. - Take a look at the constellation points and the constellation diagram of OFDM-SPM. - Understand the factors which affect the modulation and demodulation processes. - Take a look at the power levels assigned to the subcarriers, and the different power allocation policies. - Summarize the characterstics of OFDM-SPM, and what we expect it to achieve.

Simulation results: What does all that mean though?
Hello everyone, We're back and today we'll be looking at how OFDM-SPM actually performs, through Matlab Monte Carlo simulations. Does OFDM-SPM perform as expected, does it perform better or perhaps worse? Specifically, in this video, we: - Introduce the environment which our simulations were done in, and the metrics which were used to measure performance. - Go over the simulations results of OFDM-SPM when using the power saving policy. - Go over the simulations results of OFDM-SPM when using the power reallocation policy without optimized power levels (non-optimized power reallocation). - Go over the simulations results of OFDM-SPM when using the power reallocation policy with optimized power levels (optimized power reallocation). - Go over the simulations results of a fair comparison between OFDM-SPM with QPSK and conventional OFDM with 16-QAM. - Summarize what the simulation results overall tell us about OFDM-SPM. - Display how OFDM-SPM is different from other 3 dimensional modulation schemes which are available in the literature.

Conclusion and future work: Wrap it up!
Hello everyone, and welcome to our 4th and last video. In this video, we will wrap the series up by: Giving a conclusion regarding OFDM-SPM modulation. Go over future research topics which will be important to study, and will determine the future use of OFDM-SPM. Before this course ends, I would like to thank you all for attending and say that we are here to help each other, we are all pushing towards the future, and further research on OFDM-SPM could prove to be rather important given the gains it offers. Feel free to purchase the codes of OFDM-SPM with QPSK modulation from here: https://researcherstore.com/product/simulations-of-ofdm-spm-with-qpsk-modulation/ and try to add what you can to the code, there is so much to do. The code is fairly simple and is well documented. Feel free to reach out to me and professor Jehad. It's been a pleasure, this was your course instructor Abdulwahab Hajar. Take care and good luck!
