Known interference in the cellular downlink: a performance limiting factor or a source of green signal power?

摘要: Interference in wireless communications is traditionally treated as a cause of performance degradation. Whilst from statistical viewpoint this entirely justified, article discusses scenarios where the interfering signal enhances desired signal's useful power on an instantaneous basis and provides unexplored source additional power. The potential harvesting energy, which naturally exists communication system, shown to be readily available downlink systems interference can predicted. main concept discussed that instead using knowledge cancel, eliminate or avoid it, it potentially more fruitful use manipulate make towards system's advantage. A significant power, with conventional transmission techniques left unexploited, used improve radio systems' achieve reliable power-efficient benefits are yielded without need increase average transmitted
