recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

The application of the integrated solar?energy-based systems for water desalination and power production to some Iranian coastal regions has been investigated. For this purpose, Integrated Multi Effect Desalination (MED) Solar Rankine Cycle (SRC) are used. This work investigates effects main thermodynamic parameters on located at southern cities Chabahar, Qeshm, Kish Asaluyeh. each selected sit...

This paper proposes a 32 GHz band radar receiver with an X8 multiplier. The Ka-band Rx chip used in the was fabricated by using 28-nm complimentary metal-oxide-semiconductor (CMOS) process and its built-in multiplier enables to driven low reference signal of 4 GHz. designed attached ground plane microstrip patch antenna connected feedline via bonding wire. impedance matching circuit implemented...

A digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. The system is designed in Ka-band for a DVB-S2 satellite link. We use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. The six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. This approa...

aim : the aim of this study is to estimate oral cavity cancer mortality for iranian population, using bayesian approach in order to revise this misclassification. background : mortality is a familiar projection to address the burden of cancers, but according to iranian death registry, about 20% death statistics were still recorded in misclassified categories. patients and methods : we analyzed ...
