说明： 提出了正交频分复用(O FDM ) 系统中一种新的载波频偏估计算法L 载波频偏估计过程可分
为获取和跟踪, 其中, 获取过程和时间同步是同时完成的L新算法可实现的最大载波频偏获取范围
是整个信号带宽的一半L新的跟踪算法是一个最大似然算法, 在加性白噪声高斯信道(AW GN ) 下,
当N (训练序列长度的一半) 等于128 时, 其性能比Schm idl 算法提高约7127 dB 在多经信道下, 当
信噪比不是很高时, 新算法仍具有优势L(new carrier f requency offset est imat ion scheme in o rthogonal f requency

HOS_MIMO
This package contains the MATLAB code for the algorithm proposed in the following
papers. The file "mimo_main.m" is the implementation of the algorithm in the papers.
The goal of this Matlab script is to identify a MIMO system with white inputs based
on the second and higher-order statistics of the outputs only. This code will plot
the blind estimation results using figures.(This package contains the MATLAB code for t he algorithm proposed in the following papers.
