Description: 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，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个子载波的OFDM，运行此程序需2分钟－3分钟的时间。

Description:
1.利用FLEX10KE系列（EPM10K100EQC240-1X）的CLOCKBOOST
（symbol:CLKLOCK）,设计一个2倍频器，再将该倍频器2分频后输出。
对其进行时序仿真。
2.设计一个数据宽度8bit，深度是16的
同步FIFO(读写用同一时钟)，具有EMPTY、FULL输出标志。
要求FIFO的读写时钟频率为20MHz，
将1－16连续写入FIFO，写满后再将其读出来（读空为止）。

3.设计一个数据宽度8bit，深度是16的异步FIFO（读写时钟不相同），
当读写时钟的频率分别为wrclk＝40MHz、rdclk＝20MHz时，仿真其逻辑波形。
