BDS-GPS-single-frequency

用matlab的gui编写的DTMF双音多频信号生成与检测的演示程序，运行方法见readme，希望能对大家有所帮助。(Matlab by the gui prepared DTMF DTMF signal generation and detection demo program, run method see readme, for all of us hope to be helpful.)

说明：  高通滤波器，带通滤波器，数字FIR滤波器(The Shannon entropy is a measure of the average information content one is missing when one does not know the value of the random variable. The concept was introduced by Claude E. Shannon in his 1948 paper "A Mathematical Theory of Communication". Shannon s entropy represents an absolute limit on the best possible lossless compression of any communication, under certain constraints: treating messages to be encoded as a sequence of independent and identically-distributed random variables, Shannon s source coding theorem shows that, in the limit, the average length of the shortest possible representation to encode the messages in a given alphabet is their entropy divided by the logarithm of the number of symbols in the target alphabet. )

说明：  PAM调制，实现模拟信号的数字抽样，能够启发matlab初学者的编程(PAM modulation, realize simulation signal digital sampling )

Low density parity check ....

光在散射介质中的传播，输入光子步数和吸收系数，输出光子的轨迹(A 3-D Monte Carlo Simulation of a photon propagating in scattering and absorbing media. Given an input of the number of steps (iterations) for the photon to take and the absorption coefficient of media, this function calculates a random walk and returns coordinates of final position and total final distance origin.)

说明：  LMS 和 NLMS 算法的比较，用于system identification对在学习随机过程，信号处理，滤波器的人有帮助.(LMS compared with NLAM algorithm for system identification)
