▍1. MLTimeFrequencyOffsetOFDM
技术文档:OFDM联合极大似然法,符号和载波频偏估计,利用循环前缀的冗余信息实现ML估计,不需额外插入导频,其频率估计用于跟踪模式,时间估计用于捕获模式。(OFDM ML estimator for time and frequency)

已知自变量t,因变量y,y和t满足一下函数式: dy/dt=0.001414/(1/(4.5727*10^4*k1*(1-0.02119*y)^k2)+1/k3/45727);(需要指出的是,该公式中参数可进一步合并,在本帖中并未作合并处理) 已知 t=;y=;拟合出参数k1,k2,k3。(Known independent variable t, the dependent variable y, y, and t satisfy my functional: dy/dt = 0.001414/(1/(4.5727* 10 ^ 4* k1* (1-0.02119* y) ^ k2)+1/k3/45727) (It should be noted that the equation parameters can be further consolidated in this post are not treated as a merger) is known t = y = fitting parameters k1, k2, k3.)
