摘要
OFDM是一种高效可靠、实现灵活的多载波调制方式,通过研究OFDM系统的基本原理和系统特点,结合DSP技术,采用自适应算法对系统自身的不足进行针对性改进,改善了信道容量小及差错率高的不足,提升了OFDM系统的综合性能。
Orthogonal Frequency Division Multiplexing（OFDM） is a multi-carrier modulation of efficiency,reliability and flexibility.OFDM technology in different areas of modern life is widely applied and promotion with the development of digital signal processing and ultra-large-scale integrated circuit technology in recent years.By studying the basic principle of the OFDM system and its characteristics,this paper applied DSP in the OFDM and rectified the deficiencies of the system by using an adaptive algorithm to improve the channel capacity and error rate insufficiency,aiming at enhancing the OFDM system consolidated properties.
