说明：  1.OFDM入门零基础，及其宝贵和重要的仿真建模文档。 2.通过实例将OFDM在通信系统中的各种特性描述出来。 3.文档中含有该场景下所有仿真的源代码(文档的附录最后面)，已在matlab下全部编译通过。
(1.OFDM entry zero-based, and its valuable and important documents simulation modeling. 2. By example in the OFDM communication system describe the various features. 3. A document that contains all the simulation under this scenario the source code (appendix to the final surface of the document), has been under the full compile matlab.)
