它是一种多用户功率分配算法.这是一种自私算法,当接收端和发送端没有共享信道信息时,它的实现非常简单,复杂度低.但是,当信道上有共享信息,需要共享信道-It is a multi-user power allocation algorithm. It is a selfish algorithm, when the receiver and the sender does not share the channel information, its implementation is very simple, the complexity is low. However, when the channel has to share information, need to share channel
