Efficient Low Peak Orthogonal Frequency Division Multiplexing (hELP OFDM)

Late lab scale demonstration

A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

OFDM waveform suffers from the unpredictable time domain signal (non-constant envelope), which leads to non-efficient use of electronic devices and erroneous reception time to time.


We developed an efficient signal processing algorithm that can be easily implemented digitally to modify the undesired generated OFDM signal to obtain more hardware-friendly (constant envelope) waveform.


This is a ready-to-use algorithm that can be implemented digitally in base-stations and how fats it can go to industry depends on the promotion of this work.
