A Burst SC-FDE Scheme for High-Speed Communication Based on Radar

Recently the radar-based communication has aroused a great interest in the military and academia due to its great potential in increasing performance and reducing costs. However, the application of high-speed data transmission over radar antennas requires a burst waveform robust to nonlinear power amplifiers and multipath propagation effects. Our solution is to apply burst single-carrier frequency domain equalization (SC-FDE) for data transmission, which co-exists with radar equipments in time-division multiplexing mode. In this paper, we present a system that contains a training preamble and lots of data blocks. Based on the training preamble, a joint algorithm is proposed for fast synchronization. Moreover, signals are phase-modulated to combat the effects of nonlinear analog circuits and unique words are inserted between data blocks as guard intervals to eliminate inter block interference. The proposed scheme is evaluated by both simulations and field experimental demonstrations, where bit error rate
