针对通信技术中载波同步问题,提出利用科斯塔斯环提取载波。对抑制载波的双边带调制系统建模并对其仿真分析,结果表明科斯塔斯环用于载波提取可以降低成本,减小相位模糊现象,具有一定的可行性。
For the problem of carrier synchronization in communication technology, it is proposed to extract the carrier by using Costas loop. The modeling of the double sideband modulation system with suppressed carrier and its simulation analysis show that the Costasian loop can be used for carrier extraction to reduce the cost and reduce the phase ambiguity, which is feasible.
