Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. It geometrically aligns two images the reference and floating images. Medical image registration concentrates on aligning two or more images that represent the same anatomy from different angles and are obtained at different times. In...
Spectrum sensing is a critical component of the Cognitive Radio that detects the presence of primary user signal in a channel. In this paper energy detection technique based on Neyman-pearson criterion is used to detect the presence of deterministic primary user (PU) signals in the channel. We have considered three different kinds of modulated signal such as BPSK, QPSK , DVB-T (2K mode) under additive...
A recent trend in the research of ROM-less DDFS architecture, which is endowed with high speed, low power and high SFDR features and will generate the sine or cosine waveforms within a broad frequency range. In this work one high-speed, low-power, and low-latency pipelined ROM-less DDFS has been proposed and implemented in Xilinx Virtex-II Pro FPGA. The proposed ROM-less DDFS design has 32 bit phase...
Process industries require supervisory control and data acquisition systems (SCADA) or distributed control systems (DCS) depending upon geographic distribution of the plant instrumentation. Remote operation of the hazardous field needs quite a good amount of instrumentation support for control as well as monitoring purposes. The various parameters to be monitored are pressure, flow, level, displacement,...
