摘要 在数字直放站中,由于直放站发射天线会接收到自己发出的信号,形成同频干扰,严重影响信号质量,天线隔离的效果是不够理想的。采用自适应回波消除技术,用PN序列和改进的NLMS算法,并在FPGA上实现,仿真结果表明,能够很好地估计出回声信道。 In the on-channel repeaters, the transmit antenna would received its send singal, causing same frequency interference, seriously destroy the received signal. And antenna isolation can＇ t meet the demands. So adaptive interference cancellation technology is applied. Using PN sequence and NLMS algorithm technique, and implement it on FPGA. The simulation shows that, this system can simulate the feedback channel.
