摘要
多通道无线通信系统中各通道的校准是关键技术,通过设计特定的训练序列,并采用高效的快速算法,在线实时校正阵列天线系统多个通道的幅度和相位。分析了发射通道和接收通道的性能,理论分析和计算机仿真结果表明,该算法能校正通道之间的幅度和相位误差,而且实现简单,具有较好的校准性能。
This paper presented a calibration algorithm of the multi-channels for mobile communication systems. It used a unique training sequence and a fast algorithm so that the channels error can be calibrated online, and the calibration performance of the transmitter and receiver channels is analyzed. The results of computer simulation show that this algorithm can calibrate the error of gain and phase well. And it is easy to implement because the fast aluorithm is simple.
