Description: 建立并绘制任意信号的模糊函数。已在巴克码，线性调频，脉冲信号中测试过。-This program estimates and plots the ambiguity function for any signals. I have tested it for the Barker code, chirp signal, pulse signal. for good results the length of the input vector (Ut)should be more than 7. Example- a rectangular pulse should be described as[1 1 1 1 1 1 1]. Please, give your suggestions.
it is made with the help of "xcorr" function (Author: R. Losada) in MATLAB and Ilia Iliev from TU-Sofia

Description: Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence.
a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}.
b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before
spreading and after spreading
