中文说明：更好的源码，所有的程序可以运行，希望有所帮助。 ！OFDM （正交频分复用） 是正交频分复用技术，OFDM 是 MCM 多-CarrierModulation，实际上是一种多载波调制。其主要思想是： 通道被划分成几个是饺子、 通道和高速数据信号被转换成并行低速数据流，每个通道上传输的调制。正交信号可以通过在接收端，使用相关的技术分离，这样我们可以减少在 ICI 子通道之间的相互干扰。每个通道上信号的带宽小于信道带宽，，所以每个孩子可作为在平坦衰落信道，可以消除码间干扰。而且由于每个子信道的带宽是只有一小部分的原始的信道带宽，信道均衡成为相对比较容易。
English Description：
Better source code,, all programs can run, hope to be helpful.!OFDM (Orthogonal Frequency Division Multiplexing) is Orthogonal Frequency Division Multiplexing technology, OFDM is MCM Multi - CarrierModulation, actually a kind of multicarrier modulation. Its main idea is: the channel is divided into several is jiaozi, channel and the high-speed data signal is converted into parallel low-speed data streams, modulation to transmitted on each channel. Orthogonal signal can be separated by using related technologies on the receiving end, so that we can reduce the mutual interference between the ICI sub-channels. Each channel on the signal bandwidth is less than the channel bandwidth, so every child can be as a flat fading channel, which can eliminate intersymbol interference. And because each child the bandwidth of the channel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.
