Research abstract

Nova Engineering and UCSD propose a constant envelope orthogonal frequency division multiplexing (CE-OFDM) waveform as a software improvement to the current OFDM software defined radio (SDR) implementations. The proposed waveform allows the current WNW OFDM Signal-in-Space (SiS) to be inexpensively upgraded with a constant envelope operating mode. Constant envelope operation eliminates the problematic need for linear amplification and the associated power back-off. This technique enables operation in the nonlinear region of the power amplifier (PA), gaining significant power savings. Phase II will result in the demonstration of the CE-OFDM waveform operating on the JTRS Cluster 1 Development Configuration hardware.
