Study on Simulation performance of OFDM-IDMA System

Abstract:

OFDM-IDMA system with perfect performance is the key technology of 4th mobile communication. in this paper, we simulated the performance of OFDM-IDMA in AWGN and quasi-static Rayleigh channel respectively, the simulation results indicate that the performance of multi-user is close to the single use as the increase of SNR, and the error-bits curve descends obviously, which means OFDM-IDMA system can be used to the complex electromagnetic environment and high-speed data transmission.
