A Multi-Channel Testbed For Dynamic Spectrum Access (Dsa) Networks

In views of the shortage of the wireless spectrum, the US Communications Commission (FCC) has adopted the rules that allow unlicensed devices to operate in TV bands so as to achieve better spectrum efficiency. To enable this new way of wireless communication, new technologies such as resource discovery and multi-channel resource allocation must be developed. In this paper, a multi-channel testbed is developed to demonstrate the feasibility of real-time spectrum sensing and multi-channel transmission for next-generation DSA networks.
