摘要: Dynamic spectrum access (DSA) has received much attention in research community recently. DSA is the concept which communication devices of unlicensed users are allowed to underutilized licensed frequency bands. relies on cognitive radio (CR) technology identify free bands channels through sensing. In vehicular communications, sensing affected by speed vehicles, multipath fading and shadowing. this paper, we show impact communications. Understanding how environment affects will help developing techniques that can prevent interference while allowing for utmost reuse DSA.
