On Channel Coherence in the Low SNR Regime
The current study of the low SNR fading channels focuses on two extreme cases: the coherent case with perfect channel state information (CSI) available at the receiver, and the non-coherent case with no hope to obtain the channel information at all. Most of practical channels, with a low SNR and a slowly varying channel, lies in between these two extremes. In this paper, we use training based s...
متن کاملPiggybacking Codes for Network Coding: The High/Low SNR Regime
We propose a piggybacking scheme for network coding where strong source inputs piggyback the weaker ones, a scheme necessary and sufficient to achieve the cut-set upper bound at high/low-snr regime, a new asymptotically optimal operational regime for the multihop Amplify and Forward (AF) networks.
متن کاملSecure Communication in Shotgun Cellular Systems
In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولFe b 20 06 Outage Capacity of the Fading Relay Channel in the Low SNR Regime
In slow fading scenarios, cooperation between nodes can increase the amount of diversity for communication. We study the performance limit in such scenarios by analyzing the outage capacity of slow fading relay channels. Our focus is on the low SNR and low outage probability regime, where the adverse impact of fading is greatest but so are the potential gains from cooperation. We showed that wh...
