Direct Sequence Code Division Multiple Access (DS-CDMA) system is well known wireless technology. This system suffers from MAI (Multiple Access Interference) caused by Direct Sequence users. Multi-User Detection schemes were introduced to detect the users’ data in presence of MAI. Linear Multi-user Detectors and conventional Matched Filter (MF) are simulated using gold, PN and even kasami seque...

Recent technological developments and new topology designs have made semiconductor drift detectors ideal devices for high-resolution x-ray spectrometry. In this paper the basic topology of a semiconductor drift detector with on-chip electronics specially designed for x-ray spectrometry is reviewed. These devices have been used for the first time in x-ray and g-ray spectroscopy applications. In ...
The temperature dependence of electrical resistivity was measured for three materials: a conductor (copper), a semiconductor (a carbon resistor), and a doped semiconductor (a pn junction). As expected, the resistance of the copper sample decreased with temperature and the resistance of the carbon resistor increased with temperature. The temperature coefficient of resistance of Cu was calculated...
The semiconductor laboratory of the Max-Planck-Institutes for physics and for extraterrestrial physics develops and fabricates silicon sensors for scientific experiments in astronomy and highenergy physics, as well as for industrial applications. Among them are state-of-the-art detectors for X-ray imaging and spectroscopy. Their common features are the integration of the readout electronics on ...
During the last few years, real time gamma and neutron dosimeters have been developed and semiconductor diodes are frequently used in these dosimeters. Semiconductor diodes are used to charged particle detection. For sensitizing the detector to neutrons, a converter layer is contacted on the front surfaces of them. Incident neutrons interact with the converter and produce charged particles that...
We propose a new scintillation-type detector in which high-energy radiation generates electron–hole pairs in a direct-gap semiconductor material that subsequently recombine producing infrared light to be registered by a photo-detector. The key issue is how to make the semiconductor essentially transparent to its own infrared light, so that photons generated deep inside the semiconductor could r...
