Randomized trial demonstrates improved energy efficiency in low-rate applications, suggesting effective modulation strategies.

This work aims to maximize energy efficiency while maintaining a spectral efficiency below 1 bit/s/Hz for low data rate communications.
Constructed a polynomial approximation of the non-linear clipping model.
Analyzed frequency-domain waveforms including a power spectral density formula.
Developed a quasi-optimal receiver for dual-tone transmitter schemes.
Proposed schemes outperform traditional single-tone FSK and benchmarks like OOK and PAM in energy efficiency.
Best performance achieved with tones from the same odd-index frequency grid.
Robustness to frequency-selective channels and timing offset synchronization errors was evaluated.

Chateigner et al. (2026) studied this question.
