这是我学习完成端口的时候自己写的一个小程序。其中完成端口的大致功能都有。重要的是程序简单，而且有我本人的注解。适合初学者学习。

LTE 3GPP channel modeling using matlab.   Generates the correlated tap coefficients of the MIMO tapped delay line % model to be used during one iteration of the main loop. The function % performs a double interpolation, first in the fading vector domain, % to collect the fading samples corresponding to the (sub)chip-spaced time % samples, then in the tap domain, to match the delays of the PDP to % the sample instants of the simulation. This second interpolation complies % with the description in TR 25.869
