Wireless communications knows a real progress that continues relentless as subscribers make use of new products and services using mobile devices offering more and more powerful feature sets and performance. Consequently we notice both a growth in electromagnetic radiation which can be harmful for human health, and mobile battery consumption that has to be increasingly greater with such performances. In this paper 1 we propose a new power optimization scheme that aims at reducing the transmit
