Dynamic spectrum access based simultaneous non-contiguous OFDM radar sensing and communication

Abstract

With the concept of advanced intelligent transportation systems, the integration of data with technology underway with internet of things brings the concept of always connected and cognizant vehicles as an application area. The major constituents of internet of things are connection, convergence, convenience and the connected car. Road safety and vehicular infotainment are the most emerging issues for the automakers in this regard. Implementation of vehicular safety in urban lanes requires vehicle to vehicle sensing and data communication simultaneously. Because of operation spectrum scarcity, the requirement of vehicle to vehicle sensing and communication on a single platform simultaneously empowered with cognitive radio would be cost efficient. Dynamic Spectrum Access based integrated radar sensing and wireless communication transceiver is demonstrated in this work. In the proposed hardware model a direct sequence spread spectrum radar transceiver and an non contiguous orthogonal frequency division multiplexing communication transceiver is used.
