| Abstract: | The distortions caused by non linear characteristic
of RF channels are discussed.The impacts of non line
a
r channel on mono carrier and multi carrier digital communication are compared
through simulation.The
commonly-used linearization technology for compensating nonlinear distortions is
summarized and analysed.The research and conclusions can provide impo
rtant reference for the design of RF channels linearization in high frequency mu
lti carrier digital communication systems. |
