CRC Report #CRC-RP-96-002 ANALYSIS OF INTERFERENCE EFFECTS IN SATELLITE ON-BOARD REGENERATIVE REPEATERS
نویسنده
چکیده
This report provides an introduction to the problem of analyzing the performance of satellite on-board regenerative repeaters. Two speci c group demodulator architectures are discussed: one based on a polyphase network followed by an FFT processor, and the other based on a chirp Fourier transform implemented using surface acoustic wave (SAW) devices. Due to imperfect ltering and channel separation in the group demodulator, intersymbol and interchannel interference are introduced into the demodulated output. To show how it is possible to derive error performance curves in the presence of intersymbol and interchannel interference, two di erent analysis methods are presented.

The effects of Orem’s self-care model on the nutrition status and fatigue of colorectal cancer patients
Background and Purpose: Colorectal cancer (CRC) is one of the most highly prevalent and life-threatening digestive tract cancers. CRC and its treatment are associated with numerous complications in the patients. Orem’s self-care model is a theory on clinical improvement and reducing fatigue in patients with CRC. This study aimed to investigate the effects of Orem’s self-care theor...

With the development of satellite communications, on-board processing (OBP) obtains more and more attentions due to the increased efficiency and performance. However, the large amounts of digital circuits in the OBP transponders are sensitive to the high-energy particles in space radiation environments, which may cause various kinds of single event effect. Among these effects, single event upse...

Background: Colorectal cancer (CRC) is considered the fourth type of cancer that causes death in the world. Changes in levels of Zinc (Zn), Copper (Cu), and Selenium (Se) as well as low glutathione peroxidase (GPx) activity can lead to CRC and this study was aimed to evaluate their possible use as diagnostic markers. Methods: CRC patients (n=90) were divided into three groups; newly diagnosed,...

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as Aspirin may have anticancer properties, and can be effective as a novel strategy for the treatment of colorectal cancer (CRC). The aim of this study was to assess the cytotoxic effects of Aspirin drug in CRC cell lines compared with Oxaliplatin drug in vitro. Methods: Cell viability was assessed after treatment of SW742 and SW48...
