- Multicarrier modulations attract a lot of attention ranging from wireline to wireless communications compared to single carrier modulation because of theirs capability to efficiently cope with frequency selective fading channels. Much of attentio
STUDY AND ANALYSIS OF TIMING OFFSET ESTIMATION METHODS IN OFDM SYSTEMS
- OFDM is a multi-carrier transmission technique. It converts the frequency selective fading channel into a collection of parallel flat fading sub-channels which simplifies the structure of a receiver. OFDM has been widely used in communication system

- 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
