Experimental Evaluation of the Pre-Coded Windowed OFDM Using SDR

Abstract

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation scheme used for many wireless systems such as mobile systems, wireless LAN, etc. OFDM is suited for high data rate communications systems; however, the Out-Of-Band Emission (OOBE) power is high, it should be suppressed to improve frequency utilization efficiency.
