Design of optimal phase-only filters by direct iterative search
نویسندگان
چکیده
A fast algorithm termed the direct iterative search (DE) is proposed to design the optimal phase-only filters (F’OFs) with a high Homer efficiency and high-signal-to-noise ratio ( SNR) . The DIS optimizes the phase and passband of POF in the sense of maximizing the correlation peak of the signal image and minimizing the noise passage. Simulation results show the capability of the DIS for achieving a satisfactory optimum of filter phase and passband. The optimized POFs by the DIS show sharp, high correlation peak and excellent noise tolerance.

متن کاملFilter design for CWT computation using the Shensa algorithm
Direct computation of CWT using FFT requiresO(Nlog2N) operations per scale, whereN is the data length. The Shensa algorithm is a fast algorithm to compute CWT that uses only O(N) operations per scale. The application of the algorithm requires the design of a bandpass and a lowpass filter for a given mother wavelet function. Previous design method involves multi-dimensional numerical search and ...
