 An IEEE Spectrum Article  discusses a variation on OFDM signals that could significantly lower peak to average power ratio (PAPR) and that has been developed and tested by the startup Spectral DSP. As indicated in the article “Spectral DSP took the step to remotely use the COSMOS testbed during the pandemic to test harris’ theory on the testbed’s cutting edge wireless network that spans dozens of New York City blocks, and found that the mathematical results did indeed make sense.”
