Inter-Carrier-Interference (ICI) is an effect that noticeably degrades the quality of the Orthogonal Frequency Division Multiplexing (OFDM) signal. In this work, several proposed ICI cancellation schemes have been tested using open source Software Defined Radio (SDR) named GNU Radio. The GNU Radio system used in the experiment had one Universal Software Radio Peripheral (USRP) module connected to a computer. The USRP had two-daughterboard (RFX-400) for both transmission and reception of radio signals in the 400 MHz band. The input data to the USRP was prepared in compliance with IEEE-802.11b specification. The experimental results were compared with the theoretical results of the proposed Inter-Carrier Interference (ICI) cancellation schemes.
