Key Points

This research aims to enhance communication capacity by developing effective demodulation methods for FDCU signals.
Proposed two demodulation methods using experimental and simulation approaches.
Employed a lightweight neural network for rapid demodulation at lower subcarrier counts.
Introduced the implicit temporal convergence algorithm to improve demodulation at higher subcarrier counts.
The ITC algorithm achieved 100% demodulation accuracy at 5 subcarriers with a signal-to-noise ratio of 17 dB.
Performance improvements recorded under low signal-to-noise ratio conditions using threshold constraints and Gaussian weighting.

Implication

Evaluates new FDCU signal demodulation methods, showing improved performance in high-speed communication.
