The Value of Sharing Intermittent Spectrum
We consider a model of Cournot competition with congestion motivated by recent initiatives in wireless spectrum policy to allow commercial use of spectrum assigned to government agencies. A key feature of such spectrum is that it may be intermittently available due to the incumbent government user’s activity. In our model, wireless Service Providers (SPs) compete for a common pool of customers ...

ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
Value of Sharing Data
This paper analyzes whether advertisers would be better off using data that would enable them to target users more accurately if the only way they could use this data is by sharing the data with all advertisers. I present a wide range of theoretical results that illustrate general circumstances under which an advertiser can be assured that sharing data will make the advertiser better off. I the...
متن کاملAuction-Based Spectrum Sharing
We study auction mechanisms for sharing spectrum among a group of users, subject to a constraint on the interference temperature at a measurement point. The users access the channel using spread spectrum signaling and so interfere with each other. Each user receives a utility that is a function of the received signal-to-interference plus noise ratio. We propose two auction mechanisms for alloca...
متن کامل5G Spectrum Sharing
In this paper an overview is given of the current status of 5G industry standards, spectrum allocation and use cases, followed by initial investigations of new opportunities for spectrum sharing in 5G using cognitive radio techniques, considering both licensed and unlicensed scenarios. A particular attention is given to sharing millimeter-wave frequencies, which are of prominent importance for 5G.
