investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Development of Recondensing Cryostat for PAMELA
PAMELA (Particle Accelerator for MEdicaL Applications) is a design study of a novel accelerator for cancer therapy using protons and carbon ions. The accelerator utilizes the nonscaling Fixed Field Alternating Gradient (FFAG) principle and features superconducting combined-function magnets with dipole, quadrupole, sextupole and octupole field components for steering the ion beam. The proton rin...
متن کاملMagnetic resonance spectrometer with a de SQUID detector
We describe a dc superconducting quantum interference device (SQUID) based magnetic resonance spectrometer particularly suited to measurements in the frequency range of 100 kHz to several megahertz. Results are presented for nuclear quadrupole resonance (NQR) of boron-II in boron nitride at 4.2 K, yielding {uQ = 1467 ± 2 kHz. We also present a direct measurement of the methyl group tunneling fr...
متن کاملDevelopment of a Miniature Mass Spectrometer and an Automated Detector for Sampling Explosive Materials
The development of a robust ionization source using the counter-flow APCI, miniature mass spectrometer, and an automated sampling system for detecting explosives are described. These development efforts using mass spectrometry were made in order to improve the efficiencies of on-site detection in areas such as security, environmental, and industrial applications. A development team, including t...
متن کاملMulti-detector row CT systems and image-reconstruction techniques.
The introduction in 1998 of multi-detector row computed tomography (CT) by the major CT vendors was a milestone with regard to increased scan speed, improved z-axis spatial resolution, and better utilization of the available x-ray power. In this review, the general technical principles of multi-detector row CT are reviewed as they apply to the established four- and eight-section systems, the mo...
