- 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

- Multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) is very sensitive to the carrier frequency offset (CFO), which not only affects the channel estimation but also the selection of a minimum error probability based p

- OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。-OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than

- 从抗ISI和ICI的角度来讲，总是希望能量集中在时频格点附近，而扩散到其他格点的能量越小越好，TFL正是描述这一特性的最直接的方法，从滤波器的角度看，TFL特性描述两个滤波器之间的相关性，描述TFL特性的方法包括TFL函数和TFL参数两大类，TFL函数又包含瞬时相关函数、模糊函数和干扰函数，而TFL参数包括Heisenberg参数和方向参数。 本代码使用matlab仿真常见的高斯、IOTA和HSIN等滤波器，与矩形滤波器进行对比与分析。(This code uses MATLAB to sim
