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...
Integrated crop-livestock farming systems
a substantial global increase in the demand for food of animal origin, while also aggravating the competition between crops and livestock (increasing cropping areas and reducing rangelands). The livestock revolution 1 is stretching the capacity of existing production, but it is also exacerbating environmental problems. Therefore, while it is necessary to satisfy consumer demand, improve nutriti...
متن کاملAdaptation to Climate Variability and South African Livestock Systems: Lessons for Long-term Climate Change
Adaptation Adaptation is a concept derived from evolutionary biology, which, in its strict biological sense refers to the ability of organisms to pass on their genetic material to the next generation. It is measured through genetic fitness. Another, broader view of adaptation refers to the ability of individuals or groups to respond to changes in their environment. Until the last decade or so, ...
