Two-dimensional DOA estimation of unitary transformation matrix reconstruction based on L-shaped array by Xiu WANG, Qing CHANG, Yaoli WANG

“…The estimation of the direction of arrival of two-dimensional space signals is the key problem in the field of array antennas.Although the traditional two-dimensional MUSIC algorithm has high precision,it needs two dimensional spectrum peak search and has a large amount of operation.A two-dimensional DOA estimation algorithm for L-shaped array was proposed.The output matrix was transformed from a complex value matrix to a real value matrix by matrix reconstruction and a unitary transformation matrix.This method could directly get the elevation angle of the target without conversion,which greatly reduced the amount of operation.Compared with the matrix enhancement and matrix pencil algorithm for L-shaped array,this algorithm could estimate more targets’DOA.The results of simulation show that the algorithm has a high accuracy of DOA estimation.…”

Geometry-Based Synchrosqueezing S-Transform with Shifted Instantaneous Frequency Estimator Applied to Gearbox Fault Diagnosis by Xinping Zhu, Wuxi Shi, Zhongxing Huang, Liqing Shi

“…The proposed GSSST method overcomes these limitations by implementing an intuitive geometric reassignment framework, which reassigns time-frequency (TF) coefficients to maximize energy concentration, thereby allowing fault components to be distinctly isolated even under challenging conditions. The GSSST algorithm calculates a new instantaneous frequency (IF) estimator that aligns closely with the ideal IF, thus concentrating TF coefficients more effectively than existing methods. …”

Acquisition algorithm for BOC signals in high dynamic environment by Yi PAN, Tianqi ZHANG, Gang ZHANG, Baoze MA

“…As the synchronization of binary offset carrier (BOC) signals couldn’t be realized in high dynamic environment by traditional acquisition algorithms,an acquisition algorithm based on fractional Fourier transform (FRFT) and discrete polynomial-phase transform (DPT) was proposed.Firstly,the algorithm determined how to process the received signal according to the dynamic order obtained by the order operation.And then the acquisition was achieved by searching the spectral peak of the FRFT algorithm to obtain the estimation of dynamic parameters and code phase.Theoretical analysis and simulations show that the proposed algorithm eliminates the influence of second-order doppler shift rate based on original FRFT acquisition algorithm,which can successfully capture high dynamic BOC signals.The proposed algorithm further enhances the dynamic adaptability and anti-noise performance and has superior performance in detection probability and acquisition time in comparison with other algorithms.…”
