program

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

双二进制信号是一种信号体制利用码间干扰作为一种控制方式而不是消除码间干扰(Duobinary signaling is a three level signaling scheme that uses intersymbol interference in a controlled way instead of trying to eliminate it. )
