Peak-to-average power reduction in high-performance, high-throughput OFDM via pseudo-orthogonal carrier-interferometry coding

OFDM (orthogonal frequency division multiplexing) is susceptible to high peak-to-average power due to an unstable envelope. Many solutions have been utilized in order to decrease the high peaks that are possible, but in these cases complexity is also added to the system architecture. This paper shows how Carrier Interferometry phase coding greatly reduces peaks in the signal envelope and in effect the problems associated with large PAPR.
