说明：  关于椭圆算法的，比较通俗易懂，供初学者用(Algorithm on the elliptical, more user-friendly for beginners with)

说明：  最大限度地平 FIR 逼近 （拉格朗日插值法） 拉格朗日插值是一种时域方法，导致基于多项式的筛选器的一个特殊情况。用 M 次多项式近似表示输出信号。最简单的情况 (M = 1) 对应于线性插值。让我们设计和分析将通过各种馏分拆分单元延迟的几种线性分数时滞滤波器：(Maximally-Flat FIR Approximation (Lagrange Interpolation) Lagrange interpolation is a time-domain approach that leads to a special case of polynomial-based filters. The output signal is approximated with a polynomial of degree M. The simplest case (M=1) corresponds to linear interpolation. Let's design and analyze several linear fractional delay filters that will split the unit delay by various fractions:)

主要研究无线通信系统中，调制信号的载波同步问题，利用锁相环技术实现同步的matlab仿真(This paper mainly studies the carrier synchronization of modulated signal in wireless communication system, and realizes the MATLAB simulation of synchronization by using phase-locked loop technology.)

说明：  QPSK BPSK调制解调+USRP,观察（输入、输出、眼图）(modulation and demodulation of QPSK and BPSK+ USRP)
