The lower hybrid current drive (LHCD) system plays an important role in the Experimental Advanced Superconducting Tokamak. A new data acquisition system is designed to meet the requirements of high-speed signal processing in LHCD. In this system, FPGA is used as the main logic unit and USB is used as the interface, at the same time, the system firmware program is complied. Experiments show that the...
The lower hybrid current drive (LHCD) system is an important part of the experimental advanced superconducting tokamak (EAST). The reliability of the LHCD is the precondition and key point of stabilization of EAST experiments. In the complex electromagnetic environment, the reliability of signals transmission is particularly important. With the development of field programmable gate array technology,...
This work presents a highly integrated single chip multi-functional, multi-waveform signal generator which can generate various waveforms, with digital controller inside to adapt embedded and low power applications. The proposed system is composed by Nios II, DDS (Direct Digital Synthesis) and other peripherals. Nios II is a reconfigurable, programmable and optimizable soft-core embedded CPU. DDS...
Ultra-wideband (UWB) is a modern radio technology that works at extremely low energy levels. It is popularly used in short-range, low power and low cost communications such as RFIDs. This paper presents a UWB receiver using energy detection scheme with on-off keying (OOK) modulation. A novel synchronization and detection algorithm called energy offset based scheme is investigated and used in the receiver...
