摘要： A Complex Adaptive Phase Estimation (PE) filter, as presented in some concepts of the present disclosure, is an adaptive filter that accurately estimates the phase difference between signals. For example, the PE filter can estimate the phase difference between a complex primary signal and a complex incident signal, iteratively adapting the phase of a complex exponential by minimizing the mean squared error of a complex error signal. The PE filter can demonstrate accurate phase estimation and rapid convergence, with low computational complexity and storage requirements. In addition, the PE filter construction can be simplified to support absolute phase estimation of a single complex signal. Efficient complex normalization approximation can be developed to support practical PE filter implementation in computationally restrictive environments, including systems with real-time response constraints, and systems without efficient native or functional support for division or square root operations.

摘要： A phase difference measuring device for reducing the measurement time includes: a plurality of phase difference measuring circuits (104, 105, 106) arranged in one row; and phase difference conversion circuits (101, 102, 103) connected between the adjacent phase difference measuring circuits.

The phase difference conversion circuits input the first and the second signal inputted to the phase difference measuring circuit of the former stage and give a first delay total amount (Tr1) as a total of the first delay amounts and a second delay total amount (Ts1) as a total of the second delay amounts given in the phase difference measuring circuits of the former stage to the first and the second signal, respectively for output of the first and the second signal to the phase difference measuring circuit of the latter stage.

摘要： The method determines an input phase differential (Δφ) between two input signals. A phase detector (116, 118) is provided that has pairs of transistors and a first impedance (R1) connected to a first branch carrying a first signal (Iout_left) and a second impedance (R2) connected to a second branch carrying a second signal (Iout_right). The first signal (Iout_left) in the first branch is set as a first sum of a common mode output signal (Icm) and a differential mode output signal (Idm). The second signal (Iout_right) in the second branch is set as a second sum of the common mode output signal (Icm) minus the differential mode output signal (Idm). A relationship between the first impedance (R1) and the second impedance (R2) is adjusted until a differential mode output voltage (Vdm) of the phase detector is zero. The input phase differential (Δφ) is determined when the differential mode output voltage (Vdm) is zero.
