Realization of symbol demarcation synchronous algorithm using cyclic prefix in OFDM

Mingdong Li

Abstract

Based on the analysis of ISI and ICI caused by multipath delay effect in OFDM system,the radical principle of cyclic prefix is introduced and the symbol demarcation synchronous algorithm is proposed to eliminate ISI and ICI occurring in OFDM system using cyclic prefix.Realization process about demarcation synchronous algorithm and correlative theory are analysed and the approximate expression is educed.The simulation result of performance is given in the end.
