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

cuckoosearch
This file gives the main function for the implementation of the
hybridized version of the cuckoo search algorithm by combining it with
the Nelder Mead Simplex algorithm. The method is designed to minimize
functions with a low number of dimensions in a low number of
iterations.
