提出了一种基于效用函数的功率控制方法,首先介绍了频分多址技术的优势及其固有的缺点。说明了由于多址干扰的原因,使得功率控制技术成为CDMA通信系统的关键技术以及主要功率控制措施。介绍了基于效用函数的功率控制策略和分布式控制算法。最后用Matlab仿真实现。
A power control method based on utility function is proposed. Firstly, the advantages and disadvantages of FDMA are introduced. It shows that the power control technology becomes the key technology of CDMA communication system and the main power control measure because of the reason of multiple access interference. The power control strategy and distributed control algorithm based on utility function are introduced. Finally, using Matlab simulation.
