根据D.C.CHU提出的计算CAZAC序列的算法，计算出CHU序列的matlab程序。包括自相关函数，FFT变换后的CHU序列，以及CAZAC序列的一些特性，还提供D.C.CHU的算法原文-According to the calculation made by CAZAC sequence DCCHU algorithm to calculate the CHU sequence matlab program. Including the self-correlation function,

此程序主要实现CAZAC序列的OFDM系统同步，该同步可以实现定时同步和载波频率同步。-The programme realizes CAZAC trainning symbol in OFDM systems

-latlon2km.m : to find distance between two longitude-latitude coordinate -fresspaceloss.m: to calculate freespace path loss - cazacseq.m: to generate cazac sequence - pusc.m : to generate index for pusc in wimax - FCH generator: to generate
