摘要/Abstract

摘要： 提出一种具有串联环路结构的新型数字载波跟踪环,以解决极低载噪比下高动态载波信号的跟踪问题.在输入加性高斯白噪声假设下,通过建立具有一定通用性的Z域全相位模型,对新型载波环的噪声跟踪性能进行了理论分析,推导出相位噪声方差的计算通式.根据新型载波环的具体实例,验证了理论分析结果的正确性.基于上述分析结果,对新型载波环完成了参数优化,并对其与传统载波环进行了性能比较.结果表明,在极低载噪比高动态条件下,新型载波环跟踪性能优于传统载波环.所得结论可用于评估新型载波环的噪声跟踪性能或指导其环路设计.

Abstract: A carrier tracking loop with series-connection structure is proposed to solve the tracking problem of carrier signal.The loop's universal phase model is established in Z domain to analyze its tracking performance in the case of AGWN(Additive Gauss White Noise) input,and a general formula is derived for calculating variance of phase tracking noise.The theory analysis results are verified via a specific instance of new loop.Based on the above analysis results,the loop's optimization and the comparison between the traditional and the proposed loop are done,which shows that the proposed is superior to the traditional loop under the condition of high dynamic and very low CNR (Carrier to Noise Ratio).The conclusion can be used to evaluate the receiver's tracking performance or design loop.

Key words: carrier tracking, series-connection carrier tracking loop, AGWN, phase model in Z domain, variance of phase noise
