摘要
基于OFDM系统工作原理和无线移动通信信道时频二维衰落特性,研究OFDM系统的参数(包括子载波个数和循环前缀长度)设计准则,并用一个设计实例和仿真结果加以验证说明。研究结果可为OFDM系统的设计提供理论依据。
In this paper, the criterion of parameters design including the number of subcarriers and the length of the Cyclic Prefix (CP) of the OFDM system in wireless communication channels is investigated. The research is based on the principle of the OFDM system and the time-frequency fading characteristic of the wireless mobile communication channels. Research results are proved by the simulation and can be used as the theoretical foundation when an OFDM system is being designed.
