QAM
编写一个含QAM传输的发送和接收模块
1)分别采用复基带仿真和实带通仿真两种形式
a) 实带通仿真时, 载波频率为符号率的4倍
b)发端采用滚降系数0.5的根号升余弦滤波器
2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样
3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声)
统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比
(Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

FA2
一种改进的萤火虫算法解决动态0-1背包问题。经过测试,算法就有良好的性能。(Firefly Algorithm (FA), Genetic Algorithm (GA) and Differential
Evolution (DE) have been widely used for static optimization problems, but the applications of those
algorithms in dynamic environments are relatively lacking. In the present study, an effective FA introducing
diversity with partial random restarts and with an adaptive move procedure is developed and proposed
for solving dynamic multidimensional knapsack problems. To the best of our knowledge this
paper constitutes the first study on the performance of FA on a dynamic combinatorial problem. In order
to uate the performance of the proposed algorithm the same problem is also modeled and solved by
GA, DE and original FA. Based on the computational results and convergence capabilities we concluded
that improved FA is a very powerful algorithm for solving the multidimensional knapsack problems
for both static and dynamic environments.)
