The structure design and analysis of OFDM symbol in CO-OFDM system

Abstract

The structure of OFDM symbol has great influence on CO-OFDM system. This paper first presents a typical structure of OFDM symbol with virtual subcarriers and pilots for CO-OFDM. Simulation results indicate that the proposed structure is very suitable for CO-OFDM system and with this structure performance of CO-OFDM is improved largely.
