摘要 正交频分复用(OFDM)是未来第4代移动通信的核心技术.首先介绍了OFDM的基本原理,重点研究了在理想同步状态下,不同的保护间隔(CP)、调制方式和过采样率对OFDM系统误码率性能的影响,并在给出OFDM模型的基础上,对OFDM系统实现了计算机仿真,给出了以上各因素对OFDM系统误码率影响的比较曲线. OFDM is the key technology of 4G mobile communication system. First, the basic principle of OFDM was introduced. Then, the influences of different CP, modulation modes and oversampling on the system performance is emphatically analyzed respectively under the condition of ideal synchronization. Computer simulations were conducted with the proposed OFDM system. Finally, the BER curves against these factors were given and compared.
