    Low-complexity and frequency-offset-robust synchronization algorithm based on CAZAC sequence by Fengkui GONG, Ni WEN, Guo LI, Yang GAO

    Published 2021-02-01
    “…A low-complexity and frequency-offset-robust synchronization algorithm based on CAZAC sequence was proposed, which was suitable for burst OFDM systems.A new preamble sequence was constructed based on the CAZAC sequence, and its simplified timing metric function was derived by using the combination characteristics of the sequence, and then the delay correlation and symmetric correlation characteristics were used to achieve accurate and stable timing synchronization.Furthermore, based on the new constructed preamble sequence, a weighted frequency synchronization scheme combining cyclic prefix was proposed to obtain more accurate frequency offset estimation.Simulation results show that the proposed algorithm has good synchronization performance in both Gaussian channels and multipath fading channels regardless of frequency offset, and its computational complexity is lower than the most existing representative algorithms.…”

    Research on single snapshot DOA estimation algorithm based on incompletely overlapped signal by Mingchao QU, Weijian SI, Yazhi YUAN

    Published 2021-12-01
    “…To address the problem that traditional direction-of-arrival (DOA) estimation algorithms did not fully utilize the signal characteristics of active decoys and radar, which led to poor angular resolution of anti-radiation missile, a single snapshot direction finding algorithm for polarization sensitive array based on incompletely overlapped signals was proposed.Specifically, the signal data received by the array was firstly processed by polarization smoothing.After that, exploiting the signal characteristics of incompletely overlapped signals of radar and active decoys, the constructed conjugate replication augmented matrix was differentiated to obtain each signal’s conjugate replication augmented matrix.Finally, DOA estimation results of each signal were acquired by solving a convex optimization problem.Numerical results demonstrate that the proposed method shows superior estimation accuracy and lower computational complexity compared with the conventional algorithms.…”
