Dual Channel Transmission for Coexistence of Wireless Networks

Abstract

With the upcoming pervasive deployment of wireless networks and devices on the unlicensed band, co-channel interference caused by frequency collisions among coexisting networks have become one of the major performance limiting challenges. In recent years the coexistence issue has gained increasing attention. However, many collision avoidance schemes are not applicable to multiple frequency hopped (FH) networks, mainly due to that the frequency channels of FH signals are constantly changing and the hop sequence of one network is unknown to another. In this project, we develop a dual channel transmission technique for co-channel interference mitigation and robust coexistence of multiple wireless networks. This report describes the system modeling, design, theoretic analysis, simulation and testbed implementation involved in the aforementioned framework.
