| Abstract: | The basic theory of OFDM is introduced: the multi wave carrier transmission project that information stream of single user is transferred from serial to parallel as several code streams at low speed, everyone of which is modulated orthogonally and transferred through one wave carrier. The paper presents the modulation and demodulation process of OFDM and multi frequency transmission analyzing the technology of adjusting the protection space in anti multi path interference. |
