本程序是关于三次样条差值算法的仿真，内容非常详细，希望能需要他的人有所帮助。-This program is on the cubic spline difference algorithm simulation, the content is very detailed, hope to those who need his help.

Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and i
