Description: 基于matlab的OFDM仿真程序；
我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来..
现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.-Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.

Description: OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，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。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。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，从而可以消除码间串扰。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。-OFDM (Orthogonal Frequency Division Multiplexing) that is orthogonal frequency division multiplexing, OFDM is actually MCM Multi-CarrierModulation, a multi-carrier modulation. The main idea is: The channel is divided into a number of orthogonal sub-channel, high-speed data signal into parallel low-speed data streams, modulated to be transmitted on each subchannel. Quadrature signal at the receiving end can be separated using technologies, which can reduce the mutual interference between ICI subchannels. Signal is less than the bandwidth of each sub-channel coherence bandwidth of the channel, each subchannel can be regarded as flat fading, which can eliminate inter-symbol interference. And because the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.
