We consider the decentralized provision of global public good with local externalities in a spatially explicit model. Communities (municipalities, cities, countries) decide on the localization of a facility that bene ts to all but exhibits costs to the host and its neighbors. They share the costs through transfers. We examine the cooperative game associated with this so-called NIMBY problem ( N...

دایورسیتی انتقال متعامد (مانند دایورسیتی در زمان و فرکانس) یکی از روش های ایجاد دایورسیتی در فرستنده می باشد که در سیستم هایی که تحت تاثیر فیدینگ چند مسیره قرار می گیرند بسیار کارآمد می باشد. اما در این روش? کارآمدی پهنای باند با افزایش تعداد شاخه های دایورسیتی کاهش می یابد و از این رو در سیستم های مخابرات بی سیم کمتر مورد توجه قرار گرفته است. اخیراً بیان شده است که با استفاده از نگاشت بیت های م...
