In this paper, we present the implementation of a system that identifies modulation complex radio signals. This is realized using an artificial intelligence model developed, trained, and integrated with Microsoft Azure cloud. We consider cloud-based platforms offer enough flexibility processing power to use them instead conventional computers for signal based on intelligence. tested software-de...
The magnetic alloy loaded radio-frequency system has been installed in the KEK 12 GeV synchrotron. This system is a high field gradient radio-frequency system and is designed to operate not only as a fundamental harmonic system to increase the insufficient matching voltage, supplied by 4 conventional ferrite cavities but also as a second radiofrequency system to alleviate the space charge effec...
مسأله انتساب ایستای کانال در شبکه های سلولی موبایل، عبارتست از تخصیص کانال های فرکانسی مورد نیاز سلول ها بطور ثابت و بر اساس پیش بینی های و تخمین های قبلی از ترافیک هر سلول، بطوریکه دو هدف عمده کاهش انسداد مکالمات و کاهش هزینه شبکه برآورد شود. با توجه به np-complete بودن این مسأله تاکنون تلاش های زیادی جهت استفاده از الگوریتم های مکاشفه ای گوناگون در حل آن بکار گرفته شده است. اتوماتای یادگیر س...
(57) ABSTRACT A method of reducing poWer consumption of a radio badge in a boundary detection localization system is disclosed, in Which the radio badge is carried by a tracked target and performs location sampling communication With an infra structure component of the localization system at the start and end of sampling time intervals such that positions of the radio badge can be estimated. Th...
in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...
In this article we review the fundamental issues involving the simulation of the radio channel and discuss some of the more challenging simulation topics that are pertinent to the radio channel. Radio and propagation channels The propagation channel, together with the transmit and receive antennas, constitute the radio channel. Figure 1 depicts the propagation and radio channel's place in a rad...
abstract purpose of this paper: the purpose of this article is to review some of the most prominent applications of rfid in industries and to provide a comprehensive review of the work done from 1985 through 2007 and the research trend on that. the effectiveness of rfid and the challenges that it is facing with are also discussed. some applications of radio frequency identification in supply ch...
Using request radio shows as a base interactive model, we present the Steerable Optimizing Self-Organized Radio (SoSoRadio) system as a prototypical music recommender system with robust automatic playlist generation. This work describes a web-based radio system that interacts with current listeners through the selection of periodic request songs from a pool of nominees.
A lot of hardware components are used to make a conventional radio communication system, the complexity of these hardware can be reduced with help of Software Defined Radio (SDR) which is a form of wireless communication. Software Defined Radio implemented system allows us to make alteration in it or operate it with help of a software, thus making the system flexible and reconfigurable. The sys...
سیستم های مخابراتی چند ورودی چند خروجی mimo به دلیل ارتقاء نرخ مبادله داده ها و همچنین افزایش قابلیت اطمینان سامانه های مخابراتی در امور تجاری و نظامی کاربردهای زیادی پیدا کرده زیادی پیدا کرده و به همین دلیل مورد تحقیق بسیاری از پژوهشگران دانشگاهی و صنعتی قرار گرفته. با توجه به تلاش های انجام شده در این زمینه هنوز یک بستر مناسب تحقیقاتی از این سیستم ها در اختیار دانش پژوهان قرار ندارد. در این پ...
