Efficiency Improvement of Vehicular Antenna Systems for Ubiquitous Intelligent Systems
This paper describes the design of a high-efficiency vehicular roof-mounted antenna for wireless access for vehicular environment (WAVE) communication systems used for ubiquitous intelligent systems. The main objective of the ubiquitous intelligent system’s automotive IT technology is to enhance the connectivity among vehicles to ensure seamless communication and to reduce the initial access ti...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Ubiquitous Positioning Technologies for Intelligent Navigation Systems
Recently new location technologies have emerged that can be employed in modern advanced navigation systems. They can be employed to augment common satellite positioning techniques (GNSS) and dead reckoning as they offer different levels of positioning accuracies and performance. An integration of other technologies is especially required in indoor and outdoor-to-indoor environments. The paper g...
متن کاملThe Future of Intelligent Ubiquitous Computing Systems
Many ubiquitous systems and technologies have been developed as of now. As known the goal of ubiquitous computing is to achieve the wellbeing life. There are four different aspects for achieving ubiquitous computing, namely, they are within the computing paradigm, technical principle, application domain and application space. Nowadays, ubiquitous city (U-city) is the most applicable domain in t...
متن کاملHybrid Intelligent Systems in Ubiquitous Computing
Now ubiquitous computing, ambient intelligence and smart cooperative objects are viewed as a major paradigms shift from conventional desktop application development. This view is enabled through the use of diverse hardware (sensors, user devices, computing infrastructure etc.) and software, anticipating user needs and acting on their behalf in a proactive manner (Weiser, 1991; Satyanarayanan, 2...
