Stop-and-wait ARQ is a method used in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order. It is the simplest kind of automatic repeat-request (ARQ) method. A stop-and-wait ARQ sender sends one frame at a time it is a special case of the general sliding window protocol with both transmit and receive window sizes equal to 1. After sending each frame, the sender doesn t send any further frames until it receives an acknowledgement (ACK) signal. After receiving a good frame, the receiver sends an ACK. If the ACK does not reach the sender before a certain time, known as the timeout, the sender sends the same frame again.

求解出在最小均方误差滤波器单位冲激函数h(n)。求解过程需要通过利用循环嵌套的编程思想，比较在逐次增加滤波器阶数的过程中得到的最小均方误差与最初设定的最小均方误差的阈值，当达到要求时，可以进一步确定滤波器的阶数。(how to use this function: [hx,hy]=wiener_ch2(w,N) )

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

基于新的树编码方式用免疫遗传算法解决DCMST问题：提出了一种新的树编码方式，可以方便地表达一棵树，简化了树在遗传算法中的编码表达。且新的树编码方式清楚地表达了边的信息，有利于疫苗的设计。此外，本文使用免疫遗传算法，有效地克服了传统遗传算法中解退化的现象。数值实验表明，解的振荡相对于传统遗传算法减小了，且收敛速度更快。(New tree-based encoding genetic algorithm with immune DCMST problem: A new tree encoding, you can easily express a tree, the tree simplifies the code in the expression of genetic algorithm. And new tree encoding side clearly expressed information is conducive to vaccine design. In addition, we use the genetic algorithm can effectively overcome the traditional genetic algorithm, the phenomenon of degradation in the solution. Numerical experiments show that the oscillation of solutions with respect to reducing the traditional genetic algorithm, and the convergence faster.)
