ofdm仿真
OFDM即正交频分复用技术,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)

C# 代码演示水仙花求和算法
C# 代码演示水仙花求和算法,关于求和水仙花数的原理:一个三位数,每一位数的立方相加等于该数本身。清空listBox1控件,获取3位数中的后两位数。具体代码可看下面:
//水仙花数的算法是一个三位数,每一位数的立方相加等于该数本身。
private void button1_Click(object sender, EventArgs e)
{
int a = 0, b = 0, c = 0;//定义变量
listBox1.Items.Clear();//清空listBox1控件
for (int i = 100; i
