Energy efficient estimation of a MIMO channel
Exploiting the benefits of multiple antenna technologies is strongly conditioned on knowledge of the wireless channel that affects the transmissions. To this end, various channel estimation algorithms have been proposed in the literature for multiple-input multiple-output (MIMO) channels. These algorithms are typically studied from a perspective that does not consider constraints on the energy ...
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...
Distributed Energy Efficient Channel Allocation
In the last few years the issue of energy-efficient network design has gained increasingly more importance [1], [2], both in academia and in industry. Information and communication technologies (ICT) represent about 2% of the entire world’s energy consumption, and the situation is likely to reach a point where ICT equipments in large cities will require more energy than is actually available [3...
متن کاملEnergy and spectral efficient Doppler diversity transmissions in high-mobility systems with imperfect channel estimation
This paper studies energy and spectral efficient Doppler diversity transmissions in the presence of imperfect channel state information (CSI). Fast time-varying fading in high-mobility communication systems introduces Doppler diversity that can benefit system performance. On the other hand, it is more difficult to estimate and track fast time-varying channel; thus, channel estimation errors mig...
متن کاملEnergy-efficient channel estimation for multiband UWB systems in presence of interferences
Interference reduces the performance of a correct data signal detection and decoding. This problem becomes severe when interferences exist during the period of channel estimation. This will destroy the accuracy of channel estimation, and will eventually result to severe degradation in the performance of signal detection and decoding in the entire data packet/frame. In this article, we propose a...
