VC.NET 解压和压缩大文件的例子
VC.NET 解压和压缩大文件的例子,操作方法上可能和现在主流的WinRAR软件有些不一样,先设置好未压缩文件名、压缩后文件名、未解压文件名、解压后文件名方可进行操作。解压后的文件是mdb格式,压缩文件的格式为zip,用现在的Winrar就可以解压打开文件,本源码还是很有参考价值的。

ofdm仿真
说明: 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.)
