Abstract

The Orthogonal Frequency Division Multiplexing (OFDM) is one of the key technologies for new moblie communication. Multipath interference to send and receive signals. In the China Mobile Multimedia Broadcasting (CMMB) system will cause serious SNR loss, influence on the reliability of the system and timing accuracy. Through the research of OFDM technology of anti-jamming, understand many advantages of OFDM technology anti-multipath performace, combined with the simulation tool matlab simulation under Rayleigh channel, verify its under the condition of the signal-to-noise ratio of 20dB error rate have obvious improvement, proves that ofdm technology in CMMB system has a good anti-multipath performance, to improve the overall performance of the whole CMMB system, using CMMB system for navigation and timing for the future laid a good foundation.
