Abstract

A distributed non cooperative power control game with pricing (NPGP) for multiple-input multiple-output (MIMO) multi-carrier direct sequence code division multiple access (MC -DS/ CDMA) system for different modulation is considered in this work. The utility functions for assaying the performance of MIMO MC-DS /CDMA for spectral efficient communication of the system carrying wireless data are envisaged. The spectral efficiency and power efficiency are referred as utility which divulges the level of satisfaction a user may get. According to the utility functions, two NPGPpsilas are propounded, which determines the existence and individuality of the Nash equilibria. A novel power control algorithm that delves the performance of the anticipated power control games to achieve the Nash equilibria is presented in this paper. The simulated results elucidate that a significant amelioration in terms of utilities specifically spectral efficiency for all users can be achieved using this approach. Also the propounded scheme exhibits better performance in the MIMO MC-DS /CDMA in terms of spectral efficiency as compared to the traditional system.

MIMO MC-DS/CDMA系统频谱高效通信的博弈论功率控制算法

研究了多输入多输出(MIMO)多载波直接序列码分多址(MC -DS/ CDMA)系统中不同调制方式下的分布式非合作定价功率控制博弈(NPGP)。设想了用于分析MIMO MC-DS /CDMA系统的频谱高效通信性能的实用函数。频谱效率和功率效率被称为效用，它透露了用户可能得到的满意程度。根据效用函数，提出了两个NPGPpsilas，确定了纳什均衡的存在性和个性。本文提出了一种新的功率控制算法，该算法研究了预期功率控制博弈的性能以达到纳什均衡。模拟结果表明，使用这种方法可以显著改善所有用户的效用，特别是频谱效率。在MIMO MC-DS /CDMA环境下，与传统系统相比，所提出的方案在频谱效率方面表现出更好的性能。
