摘　　要：运载火箭测控系统信息传输速率的增加使得射频频谱资源日益紧张。针对目前使用的FM和BPSK调制,在基带进行频谱成型处理,以减小各无线电信号间的互相干扰。仿真结果表明,信号兼容性得到了极大改善。The radio frequency telemetry and telecommand. For FM spectrum has become more inadequate, as and BPSK modulation which are widely the data rates continue to grow for launch vehicle used today, signal spectrum shaping is processed at baseband in order to reduce mutual interference between wireless signals. Computer simulation results show that the signal compatibility is greatly improved.
