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...

User Interaction Techniques for Future Lighting Systems

LED-based lighting systems have introduced radically new possibilities in the area of artificial lighting. Being physically small the LED can be positioned or embedded into luminaires, materials and even the very fabric of a building or environment. Together with new functionality and flexibility comes complexity; the simple light switch is not anymore sufficient to control our light. This work...

Using Realistic Lighting in Modern Graphics Applications Frann Cois Sillion

ii Abstract The use of 3D graphics on workstations and PCs becomes increasingly important for modern graphics applications. Also the use of 3D virtual environments on the Internet, e.g. using the VRML standard, is promising to be a great success. In all of these applications, realistic lighting is an important feature to obtain a realistic, and thus convincing, impression of 3D objects and comp...
