Tracking speed and stability of adaptive gradient filtering algorithms represented by least mean square (LMS) are restricted for non-stationary circumstance. A joint processor which consist of the gradient lattice filter and transversal LMS linear combiner was designed, the performance of processor were investigated when the input signals were interfered by(More)
The zero shifts caused by accumulative error of open-loop numerical controlling mechanical equipments need to be manually corrected. An optical-mechanical-electrical integration technology included image analyzer, slit image and MCU are applied to constitute of a system for auto zero shift detection and auto zero returning. Firstly we utilize optoelectronic(More)
this paper introduces the application of electronic design automation (EDA) technology on the professional teaching for electronic information engineering. A signal generator based on FPGA is designed with various kinds of EDA tools including PROTEL, SOPC builder and NiosII, and using VHDL to accomplish the direct digital frequency synthesize (DDS) and the(More)
Pipelining technology can improve clock frequency through shortening the critical path of logic device. However, the complex algorithm of gradient adaptive lattice joint processing (GALJP ) results in its lower work clock frequency. A pipeline optimization approach based on the technology of delay leading transfer is proposed. By approximate treatment to(More)
In this paper, the optimal parameters of sections and step is decided by the outcome of the astringency and stability of reflectance in gradient adaptive lattice filter. An adaptive gradient lattice joint processing model of 3 sections for noise cancellation was established and simulated using a variety of EDA tools in a FPGA chip. Behavior level, register(More)
