| Abstract: | Systems are always designed and optimized based on full traffic load in the current literatures.However,practical systems are seldom operating at full load,even at peak traffic hours.Instead of maximizing system rate to achieve the full load,an optimal energy-efficient scheme to minimize the transmit power with required rates is investigated in this article.The considered scenario is a two-way relay channel using amplify-and-forward protocol of physical layer network coding,where two end nodes exchange mess... |
