Waveform design and processing in OFDM based radar-communication integrated systems

This paper presents an integrated radar and communication system using a unique platform to meet the requirements of future intelligent transportation networks. A phase-coded orthogonal frequency division multiplex (PC-OFDM) waveform in which the phase sequence being controlled via transmitted messages is given. A radar data processing algorithm that is able to achieve the joint estimation of the range and velocity simultaneously, for the single-scatter-point target is presented within one single transmitted pulse. Moreover, the performance analysis of the radar algorithm is analyzed in detail. Theoretical analysis and numerical results show that, the presented methods can achieve higher-resolution range-velocity profiles of the targets along with the relative high data rate transmissions.
