Abstract :
OFDM is the key technology of 4G in the field of mobile communication. In this article basic principle of OFDM is briefly introduced. Then, the influence of CP and different channel estimation on the system performance is emphatically analyzed respectively in Gauss and Rayleigh fading channels in the condition of ideal synchronization. Besides, based on the given system model OFDM system is computer simulated with MATLAB language, and the BER curves of CP and channel estimation are given and compared.
