  • Distributed noncooperative power control game for wireless data is considered in multiple-input multiple-output (MIMO) CDMA system. Utility functions are established for wireless data over the MIMO CDMA system. The spectral efficiency and power efficiency are both referred to as utility which reflects the level of satisfaction a data user gets. According to the utility functions, two noncooperative power control games are developed, and establish the existence, uniqueness of the Nash equilibria of them. The pricing mechanism is studied for the power control games. We also present power control algorithms to get the Nash equilibria and analyze the performance of the proposed power control games.
