现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,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.希望大家能从中得到你需要的东西. -Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel e

对OFDM信道建模，包括普通IDFT算法和IFFT快速算法-For OFDM channel modeling, including general IDFT algorithm and fast algorithms IFFT

lte中上行链路scofdm调制方式的实现过程，包括dft，idft和ofdm过程-lte uplink scofdm modulation implementation process, including the dft, idft and ofdm process

Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and i
