Abstract
In this paper, we propose novel spectrum sensing algorithms to detect multi-channel CR signal in TV white space. Most of CR systems in TV white space are considering multi-channel operation to support enhanced system throughput. Therefore, spectrum sensing algorithm to detect multi-channel CR system is essentially required for coexistence in TV white space. The proposed algorithms can detect various types of multi-channel CR signal with reasonable detection performance. By employing the proposed algorithms, we can contribute to efficient implementation of spectrum sensing process as well as intelligent coexistence mechanisms in TV white space.
