channel 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...

Knowledge - Based Diagnosis for Aerospace Systems

Reusable Software Architectures for Aerospace Systems∗

Modern, complex control systems for specific application domains often display common system design architectures with similar subsystem functionality and interactions, making them suitable for representation by a reusable specification architecture. For example, every spacecraft requires attitude determination and control, power, thermal, communications, and propulsion subsystems. The similari...

Intelligent Systems For Aerospace Engineering--An Overview

1 Abstract Intelligent systems are nature-inspired, mathematically sound, computationally intensive problem solving tools and methodologies that have become extremely important for advancing the current trends in information technology. Artificially intelligent systems currently utilize computers to emulate various faculties of human intelligence and biological metaphors. They use a combination...

MEMS, Microengineering and Aerospace Systems

Microelectronics processing technology spawned a new area of science and engineering exemplified by the acronyms MEMS (microelectromechanical systems) and NEMS (nanoelectromechanical systems). Microengineering is a multidisciplinary investigation of the physics and science of the submillimeter scale world and the application of this understanding to develop mass-producible microdevices and syst...
