随着蜂窝移动通信市场的巨大发展，下一代通信将是移动多媒体通信。这种情况产生了一个问题，如何对语音信源以外的多媒体信源进行功率控制。在探讨这个问题上，我们引入微观经济学中的数学模型和概念以及博弈论理论。在本文中，电话的通话质量被称为“效度”，对于一个CDMA电话通信的分布式功率控制被看作是一个‘非协作的博弈’。(CDMA mobile communication system is a technology which will be used in the next-generation communications system, so wideband CDMA technology has been unprecedented attention, and a large number of improved algorithm to improve the performance of CDMA system has emerged in its various research on key technologies.)
