摘要
采用软件无线电技术实现遥测发射机的高码率数字化调制,构建一个开放、标准、通用的硬件平台,FM体制最高调制码速率可达20Mb/s。设计中还采用脉冲成形技术对调制信号进行预调处理,极大地提高了系统的频带利用率和射频功率的发射效率。
In this paper,the software radio technology is used to achieve high bit rate telemetry transmitter digital modulation.An open,standard,common hardware platform is built.The FM system's maximum bit rate is up to 20Mb/s.The pulse shaping technology is also used in the pre-set process of the modulation signal,which makes the RF transmitter power efficiency and system bandwidth efficiency greatly improved.
