SNR Estimation of OFDM Adaptive System in Gauss Channel

Abstract:

The technology of OFDM is a multi-carrier technology, and it is a kind of high efficient modulation technique, it has the ability of strong anti multi-path propagation and frequency selective fading, and higher frequency spectrum utilization rate, this technology is applicable to high speed data transmission in the multi-path and fading channel environment. This paper introduces the basic principle of OFDM adaptive system, and the SNR estimation of OFDM adaptive system in Gauss channel through the simulation, this is a theoretical foundation to practical application in the future.
