这个程序是基于ＭＡＴＡＬＢ平台实现的，由于本程序是自己编的，所以还有不足的地方如那位大侠有好的建议请提出(This procedure is based on the MATALB platform, as a result of this process is allocated its own, so there are less than places such as the heroes who have put forward good suggestions, please)

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
