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
針對某遙測遙控全數字接收機的研製，對相干載波同步中的鎖相環、鎖頻環、 dpll 、本地nco等進行了詳細的分析和優化設計，在fpga上實現了高動態全數字ds - qpsk接收機中的載波同步模塊，解決了大范圍和動態多普勒頻移下接收機的相干載波提取與跟蹤問題。 -
