多FFT解调可与相干或差动相干检测可以应用。差异相干检测可能对时变信道的优点，其中相干检测患有通道  估计误差。最好是在频域中执行的差分编码，即在整个OFDM载波。在可供下载的源代码包在http://millitsa.coe.neu.edu/?q=projects，多FFT解调与差分相干检测和多个接收元件（空间分集）来实现。

season解答的关于在NS仿真中出现的比较棘手的问题，这些问题中的很多问题在NS仿真中都会出现，而且如果对ns理解不深入的话很难及时解决，NS高手season详细解答了这些问题，在ns仿真中会起到事半功倍的效果。-season to answer on the NS simulation appears more difficult issues in many of the problems in the NS simulation will occur, but if ns does not understand the depth resolved in a timely manner, then it is very difficult, NS masters season to answer these questions in detail, in ns simulation will play effectively.
