针对移动通信系统中多径干扰的问题，主要从以下两个方面对OFDM系统进行仿真验证：1、添加循环前缀（CP），如何降低码间干扰；2、添加均衡如何进一步提高系统的抗干扰效果。

-Mobile communication system for the problem of multipath interference, mainly from the following two aspects of OFDM system simulation: 1, add cyclic prefix (CP), how to reduce inter-symbol interference　2, how to add balance to further improve the anti-jamming system effect.
