Modified jakes model implementation with Walsh Hadamard code. Autocorrelation and cross correlation are the outputs

GPOPS是一个可以进行大规模非线性优化的MATLAB工具箱.(GPOPS, short for General Pseudospectral OPtimal Control Software is a Matlab optimal control software designed to implement the Gauss and Radau hp-adaptive pseudospectral methods. These methods approximate the state using a basis of Lagrange polynomials and collocate the dynamics at either the Legendre-Gauss or Legendre-Gauss-Radau points. )

Lab 2 – Synthesizable MATLAB This lab exercise will explore the effects that different MATLAB coding styles have on hardware. The lab has two parts, each of which begins with a short introduction. This lab exercise is based on the simple MATLAB FIR filter model shown below:(Lab 2- Synthesizable MATLABThis lab exercise will explore the effects that different MATLAB coding styles have on hardware.

DISTEU Function DISTEU Pairwise Euclidean distances between columns of two matrices Input: x, y: Two matrices whose each column is an a vector data. Output: d: Element d(i,j) will be the Euclidean distance between two column vectors X(:,i) and Y(:,j) Note: The Euclidean distance D between two vectors X and Y is: D = sum((x-y).^2).^0.5

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)
