In the present, wireless network applies in various ways; the requirement of different applications for the network resources are different. The first question in the paper is in order to meet the network transmission speed needs for different users to achieve maximum the total capacity with power management, we propose a way of low complexity and high accuracy to improve the method so that a better system performs. And in the second question, we proposed choosing several methods of subcarrier allocation which makes the base station transmit power needed lower.口試委員會審定書..........................................
