摘要
在卫星通信领域,OFDM技术以其卓越的性能受到人们的青睐,但他也存在一定的问题。针对OFDM系统放大器非线性失真这一问题,对3种主流预失真算法进行了研究分析,解决了相位突变问题,并通过仿真验证做出性能评估。
The OFDM technique is subjected to people＇s favor by its outstanding function, but it also exists certain problems. This text analyzes the three artery predistortion algorithms against the nonlinearity of amplifier in OFDM system, resolves the problem of phase break,and makes evaluation through computer simulation.
