值得深刻阅读的基于CP的OFDM同步程序这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波 (Worthy of profound reading of the CP-based OFDM synchronization program which is a very good based on the CP maximum likelihood symbol timing synchronization and carrier synchronization for OFDM MATLAB simulation program, after I read in-depth absorption of classical literature, repeated programming and debugging and refining made, the code refined and orderly sequence is absolutely no mistake, this program simulation synchronization curves and classic literature is exactly the same. Colleagues to read this program must benefit Generous achievements, special upload to share with you friends. Also welcome colleagues to provide more excellent program. Because the literature require the use of N = 1024 subcarriers)
