代码说明:

基于梳状导频的OFDM信道估计仿真代码。根据导频序列的不同排列方式,导频结构可以分为三种:梳妆导频、块状导频和格状导频。梳状导频的类型中,每个OFDM符号的子载波上周期性的放置导频信号,然后利用这些导频信号进行频域插值,沿频率轴进行信道估计。

    User Manual for STABLE 5.1(This manual gives information about the STABLE library, which computes basic quantities for univariate stable distributions: densities, cumulative distribution functions, quantiles, and simulation. Statistical routines are given for fitting stable distributions to data and assessing the fit. Utility routines give information about the program and perform related calculations. Quick spline approximations of the basic functions are provided. Densities, cumulative distribution functions and simulation for discrete/quantized stable distributions are described. The multivariate module gives functions to compute bivariate stable densities, simulate stable random vectors, and fit bivariate stable data. In the radially symmetric case, the amplitude densities, cumulative distribution functions, quantiles are computed for dimension up to 100. The signal filtering module includes functions to compute non-linear filters for signals with heavy tailed noise. Specifically, a novel stable fi)
