本文研究了一种用于多用户光移动通信的光自适应天线阵列系统。将相干信号源嵌入具有外球面透镜系统的球形光学相控阵中。该系统可以根据信道传输矩阵预测接收端的信号功率,并在发送信号时进行功率补偿。相应地,提出了一种纯相位无损期望光场恢复算法,并将其用于天线阵列系统的空分多址和自由功率分配。搭建了小型光学自适应天线阵列实验系统,测试结果良好,符合预期。
In this paper, an optical adaptive antenna array system for multi-user optical mobile communication is studied. A coherent signal source is embedded in a spherical optical phased cell array with an external spherical lens system. The system can predict the signal power of the receiving end according to the channel transfer matrix and perform power compensation when transmitting the signal. Correspondingly, a pure phase lossless desired light field recovery algorithm is proposed and used for space division multiple access and free power allocation of antenna array systems. A small-scale optical adaptive antenna array experimental system is built and tested with good performance and consistent with the expected results.
