FM-OFDM: A Constant-Envelope Sensing Waveform with Phase-Differencing Receiver Processing
This paper characterizes FM-OFDM as a sensing waveform based on its bandwidth, ambiguity function, sidelobe behavior, and Doppler estimation capability, and shows that its data dependent sidelobe floor is incoherent and decreases through across frame integration, whereas the corresponding CP-OFDM floor remains unchange...
