Problems of OFDM and MIMO Applied in CR Ad Hoc Network and Methods to Some of Those Problems

摘要：

Cognitive Radio ad hoc network is a promising network which can sense network environment, adapt to it, increase spectrum efficiency and optimize network behavior and performance. OFDM and MIMO are two essential technologies in CR ad hoc network, although OFDM and MIMO have their own merits to implement CR ad hoc network, there are still some challenges. In this article, OFDM and MIMO technology in CR ad hoc network are introduced, key problem of OFDM and MIMO technologies are analyzed and at last, methods to conquer some of those problems are discussed including method to decrease inter cell interference, and whats more combination of MIMO and OFDM technologies in CR ad hoc network are identified.
