“…Thus, every hertz of bandwidth counts, and over the decades various optimization schemes have been implemented to maximize the utility of the available bandwidth. Recent progress in antenna and power amplifier technologies offer promising approaches to perhaps enable wider bandwidths 2 , and as a result matching waveforms are now of great interest.…”

Radio frequency (RF) communication and radar applications in the low frequency ranges (3 Hz -300 kHz ELF-LF range and beyond) form an important subclass of RF use cases that have to utilize waveforms that are inherently limited in bandwidth and hence information throughput capability. Thus, the challenge is maximizing the performance of suitable classes of waveforms in terms of throughput, noise and interference suppression, power and practical realizability. In this paper, we summarize the limitations of the traditional approach using sinusoidal waveforms, and briefly describe alternative and modified approaches using OFDM, wavelets, filter bank-based methods and optimized prolate spheroidal waveforms.
