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.)

DDKzhongwen
称它为“驱动程序超级宝典“一点也不过分,因为它是被译为中文的MSDN DDK文档。这个文档不是我翻译的,我只不过将它编辑了一下。翻译它的同志是个高手,非常专业,在此先谢谢他给我们作的工作。
( Called it is "the driver super precious book" not excessively,
because it is translated for Chinese MSDN the DDK documents. This
documents are not I translate, I only have edited it. Translates it
comrade is a master, extremely specialized, first thanks him in this
the work which does to us. )
