• The principle and structure of pll ( phase - locked loop ) , including fll and loop filter , are analyzed and described . the module of carrier synchronization in the all - digit ds - qpsk receiver was carried out in the fpga chip . the problem about the estimation and track of the correlative carrier frequency under high dynamic circumstances was resolved very well
  针对某遥测遥控全数字接收机的研制,对相干载波同步中的锁相环、锁频环、 dpll 、本地nco等进行了详细的分析和优化设计,在fpga上实现了高动态全数字ds - qpsk接收机中的载波同步模块,解决了大范围和动态多普勒频移下接收机的相干载波提取与跟踪问题。
• This dissertation adopts a universal digital ds / dmpsk modulation and demodulation scheme which is based on fpga . this scheme adopts quadrature balanceable modulation , intermediate frequency sampling , digital matched filtering , delay differential demodulation techniques and so on . it directly processes the digital signals on intermediate frequency without down - conversion , and doesn ’ t need pseudo random codes synchronization and carrier wave extraction circuits
  本文采用了一种基于fpga的通用数字调制解调方案,该方案在调制端采用了正交平衡调制技术,在解调端采用了中频带通采样、数字匹配滤波、延时差分解调等技术,直接在中频上进行数字信号处理,不需要进行下变频,也不需要增加额外的伪随机码同步捕获和载波提取电路。
