包括两种算法的信道估计，lmmse和ls算法，文件还包括一个小m序列的产生函数，可以方便的产生需要的小m序列-There are two types of channel estimation algorithm, lmmse and ls algorithm, the document also includes a small m sequences and functions, can easily generate the required small m sequence

基于matlab的ofdm系统仿真，通过仿真实现了ls 和LMMSE准则的信道估计，并仿真比较了两种方法的性能-Matlab ofdm systems based on the simulation, the simulation criteria to achieve the ls and LMMSE channel estimation, and simulation performance of the two methods compared

简单OFDM系统的信道估计算法LS和LMMSE，有误码率比较图

对信道估计技术进行仿真，包括基于LS的信道估计、基于LMMSE的信道估计，以及在加入DFT后两种算法对应误码率和均方误差性能比较的仿真。
