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

Ant_clony_of_alogrithm
基本蚁群聚类算法及其改进算法[带Matlab源代码]
该算法，解决了不收敛的问题，聚类效果非常好（效果图如附件图片所示）。
改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子，
产生变异，从而更快的收敛。
(The basic ant clustering algorithm and its improved algorithm with Matlab source code of the algorithm to solve the non-convergence problems, the clustering effect is very good (image such as shown in the attached images). Improved ant colony algorithm is a genetic algorithm-based improvements in the basic genetic algorithm based on the added factor of variation, mutation, and thus faster convergence.)
