Direct_sequence_spread_spectrum
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

模式搜索法源程序。模式搜索方法是求解最优化问题的一种直接搜索方法,它不用目标函数与约束函数的导数信息而只用函数值信息,是求解不可导或求导代价较大的最优化问题的一种有效方法。(Source model search. Pattern search method for solving optimization problems is a direct search method, it should not be the objective function and constraint function information of the derivative function only information is the solution of non-derivative or derivative of the cost of a larger optimization problem of a effective way.)
