| 摘 要： | 编码正交频分复用(COFDM)是一种多载波数字通信调制技术,其基本原理是将频域中的一个宽带信道划分成多个重叠的子信道进行窄带传输.在接收端,虽然频谱相互重叠,但是只要保证各子信道上信号的正交性,就可以将各信道上的信号正确分离.文章重点研究了COFDM 通信系统中的同步技术.

| Abstract: | Code Orthogonal Frequency Division Multiplexing (COFDM) is a multi-carrier digital communication modulation technology.Its basic principle is to divide a wideband frequency channel into multiple overlapping subchannels for narrowband transmission.Despite of the spectral overlap,the signals on the subchannels can be correctly separated at the receiver side as long as they are orthogonal.This dissertation focuses on the research on the synchronization technology in COFDM communication systems. |
