- Cognitive Radio (CR) technology is one of the favorable technology to efficiently deploy the underutilized frequency spectrum. Currently, the Federal Communications Commission (FCC) allowed TV white space (TVWS) which should protect the licensed user communication to utilize for data communication. The first actual deployment of communication system operating on TVWS is implemented in our group. However, it operates in SISO and single-channel procedure. So, we will develop a second version test-bed operating various modes such as SIMO, 2×2 MIMO and multi-channel communications. From these diverse operation methods, we expect that data rate is enhanced. In this paper, we will introduce a CR RF transceiver which is equipped in our second version of test-bed based on ECMA-392 international standard. © 2011 IEEE.
