In this paper we analyze the cancellation of the interference caused by a Intelligent Transportation Systems (ITS) on devices operating in the Dedicated Short Range Communications (DSRC) framework. The cancellation is operated by an interference canceller based on the active feed-forward architecture. The canceller is designed to operate over the frequency band 5.2 GHz – 6.4 GHz, hence it is suitable for the mitigation of mutual interference on signal pertinent to DSRC at 5.8GHz due to ITS signals at 5.9 GHz. When applied to a Road Side Unit (RSU) for electronic toll collection (ETC) operating at 5.8 GHz, the proposed technique is capable to improve the performance of the front-end by cancelling the interfering signal in the 5.9 GHz bandwidth such as IEEE 802.11p signals involved in the ITS protocols; signal-to-interference improvement of 25 dB operating on 10MHz bandwidth signal is herein reported. The paper introduces the architecture of the canceller as well as the experimental results which describe the capability of the technical approach.
