一种压缩感知信号恢复算法，针对贪婪迭代类算法中的正交匹配追踪（OMP)算法的改进。OMP在每次迭代过程中选择出的原子并不是最优的，无法使本轮迭代中残差的减少最大化。本例程实现了改进的最优OMP算法，即Optimised_OMP，保证每次迭代选出的原子与已选出的原子序列所构成的平面正交，因而可以使残差下降的更快，从而加速算法收敛。(A compressed sensing signal recovery algorithms track (OMP) algorithm and orthogonal matching algorithm greedy iterative class. The OMP selected atoms in each iteration of the process is not optimal, not be able to maximize the reduction of the residual in the current round of iteration. The routines to achieve the optimal OMP algorithm improvements that Optimised_OMP, to ensure that each iteration selected atoms with atomic sequence elected a plane orthogonal, and thus can make the residuals have declined even faster, thus speeding up the algorithm convergence.)

Verilog实现的定时同步gardner算法，工程中包括整个定时环路的Verilog实现。主要模块包括：内插滤波器，定时误差检测器，环路滤波器和数字振荡控制器。同步是通信系统中的一个非常重要的内容，由于收、发端不在一起，要使它们能步调一致地协调工作，必须通过同步系统来保证。同步系统工作性能的好坏，很大程度上决定了通信系统的质量。
