说明：  通过仿真表明，该算法同几种经典的分布式算法相比，不但降低了发送功率，提高了用户效用，而且有较好的收敛性能，适用于对时延特性要求较高。
(Through the simulation shows that this algorithm with several classic distributed algorithm, not only reduce the sending power, improve the user utility, and has better convergence performance, suitable for time delay characteristic request is higher. )
