本程序是用matlab程序语言编写的costas环仿真程序，并对于模拟的costas环的性能进行了分析，costas环主要用于载波同步，本设计实现了对于载波频率跟踪的实现，并且给出图形对比(The program is written in matlab program costas loop simulation program, and the simulated performance of costas loop analysis, costas loop is mainly used for carrier synchronization, the design achieved the realization of the carrier frequency tracking, and gives graphic correlation)

研究了重频参差相参脉冲串的频率估计算法。通过脉内相关积累，提高了新序列的信噪比。对新序列的相位差按参差重数抽样平均，减小了等效的相位噪声方差，利用重频参差比解相位模糊，扩大了频偏允许范围，降低了算法的信噪比门限。分析了本算法实现相参频率估计的条件，推导了相应信噪比门限的解析表达式，指出了信噪比门限与信号样本总数、参差重数、参差比之阎的关系。仿真结果表明：上述结论是正确的，在满足信噪比门限条件下，频率估计的精度接近相参脉冲串频率估计的克拉美一罗限(CRLB)。(Frequency Estimation for Staggered Coherent Pulse Train)
