Dedicated Short Range Communications (DSRC) is a MAC layer and physical layer standard designed for vehicular networks. A multi-radio based DSRC system can have several noticeable advantages, e. g., shorter hand off latency, larger bandwidth higher spectrum utilization, etc. However, Multiple-radio in DSRC system has to address several issues in terms of Signal to Noise Ratio (SNR) and the deployment. In this paper, we prove that multi-radio DSRC is feasible in future vehicular networks. We evaluate free-space path loss and optional adjacent channel rejections. We analyze the SNR of modulations in DSRC Orthogonal frequency-division multiplexing (OFDM) system, and study the performance of BER according to SNR and FEC. The isolation requirement of antenna pair is discussed later in this paper. We also analyze applicable decoupling methods and technologies to achieve the decoupling requirement. At least one decoupling method could meet the isolation requirement of multi-radio system and can be used in the future multi-radio DSRC networks. This point is supported by our experiment results. |
