代码说明:

    Matlab中如何求一个序列的极值?在Matlab中有专门求序列最大值和最小值的函数,分别是Max  和  Min,但是有时候我们不满足于求整个序列的最值,而是对序列的极值,也就是局部的最值感兴趣。对于解析函 数,这个比较简单,只要令一阶倒数为零求出对应的自变量就行了。(Matlab how to seek a extremum sequence? In the Matlab there is a special function for sequence of maximum and minimum values, respectively is Max and Min the value, but sometimes we do not meet for the whole series, but the extremum sequence, also is the value of local interest. For analytic functions, this is relatively simple, as long as the countdown to zero order and related variables on the line.)

    主要用途是对抗多径衰落。由于多径衰落的存在,使得同一个帧由于路径不同,到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰,影响 性能。另外,由于有了循环前缀,使得IFFT FFT操作把原来的线性卷积变成循环卷积,大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)
