| 摘 要： | 为了提高笔记本终端无线网络的性能,考虑采用方向图可重构多输入多输出天线(MIMO).由于室内周围人的移动对网络传输性能的影响,提出了基于可重构天线辐射状态的选择算法.它的基本原理是,可重构天线的辐射状态对应着信道的传播状态,选择最佳辐射状态对应着选择最佳信道传输状态,也就是最大化信道矩阵的Frobenius范数.理论研...

| Abstract: | In order to enhance the performance of wireless network of the notebook terminals,Multi-input Multi-output(MIMO) systems with reconfigurable radiation pattern is evaluated.Considering the influence of peoples' moving on the performance of the network transmission,we propose an antenna algorithm based on the state of radiation pattern of reconfigurable antennas.The algorithm is based on the fact that the radiation states of the reconfigurable antennas are corresponding to the channel states and optimizing ra... |
