综合数字环路载波是互联网通信中经常使用的术语。
本文着重研究全数字QAM接收机中载波恢复环路的设计,采用快慢两个数字环路来进行载波恢复。
The design of the carrier recovery loops in an all-digitized QAM receiver is investigated and two cascaded digital carrier recovery loops are proposed.
对环路中的各部件参数等进行了设计与仿真,建立了环路的动态仿真模型,验证了算法的正确性,并且得到了数字化载波同步环路设计的一些经验值。
Then we validate the algorithm's correctness by establishing a dynamic simulation model of the loop, in which we obtained some experiential values of certain parameters.
