Phase-only filter with improved discrimination.
نویسندگان
چکیده
The optimization of a phase-only filter (POF) in terms of discrimination capability is presented. The notion of a phase-difference histogram and its modification are proposed for selecting the support function of the POF. Some numerical results obtained with the conventional POF and the optimized POF are given. The discrimination capability is increased significantly.

Improved FIR filters for discrimination of damped sinusoids
It is shown that the FIR filter based discrimination of damped sinusoids can be improved by removing the linear phase constraint. The resulting filter is not only economical and better suited to processing of shorter data records, but also offers superior numerical conditioning and therefore reduced error and sensitivity to perturbations. Zusammenfassung Gezeigt wird, da13 die auf FIR-Filtern b...
متن کاملEnhancing the discrimination capability of phase only filter
This paper establishes the equivalence of the phase only filter and a complexvalued neural network, and then shows how neural network learning can be utilized to enhance the capability of phase-only-filter based system. Specifically, the capability of phase only filters in pattern matching tasks is enhanced by using complex-valued, neural network learning algorithms. By incorporating the neural...
متن کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملHarmonic segregation through mistuning can improve fundamental frequency discrimination.
This study investigated the relationship between harmonic frequency resolution and fundamental frequency (f(0)) discrimination. Consistent with earlier studies, f(0) discrimination of a diotic bandpass-filtered harmonic complex deteriorated sharply as the f(0) decreased to the point where only harmonics above the tenth were presented. However, when the odd harmonics were mistuned by 3%, perform...
