In this article, timing synchronization in OFDM is attained with the help of Zadoff–Chu sequence as a training symbol. An algorithm based on the cross-correlation property of fractional Fourier transform (FRFT) is proposed to generate a new timing metric. In this algorithm, cross correlation of received signal and Z–Chu sequence is taken at the receiver side in FRFT domain. The mathematical analysis...
OFDM radar has been studied in the last years for its suitability to combine communication and radar applications simultaneously. In this paper, we discuss the processing applicable to a train of OFDM pulses as from a radar prospective. We will focus on two different solutions. The first solution operates on the time domain signal while the second solution processes the signal in the frequency domain...
Orthogonal frequency division multiplexing (OFDM) radar is highly appropriate in applications where communication and radar functionalities are intended simultaneously. The same waveform and the same infrastructure are used, reducing hardware complexity. In this paper, we focus on the radar processing of a pulsed waveform, where the pulses are composed of several OFDM symbols. We derive a novel signal...
