Abstract

<P>Today, access to radio spectrum is largely based on the principle of fixed resource allocation&#046; With the proliferation of wireless applications/services in the last couple of decades, in many countries, most of the available spectrum has been allocated&#046; This results in the radio spectrum scarcity which poses a serious problem for the future development of the wireless communications industry&#046; On the other hand, careful studies of the usage pattern reveal that most of the allocated spectrum experiences low utilization&#046; This motivates the concept of dynamic spectrum access via cognitive radio technologies, which allows secondary networks to use unused or under&#8211;utilized radio spectrum from primary licensed networks&#046; </P><B>Keywords:</B> <P><STRONG>Policy and Economics Track:</STRONG><BR> <TABLE cellSpacing=0 cellPadding=5> <TBODY> <TR> <TD style=&#8243;WIDTH: 45%&#8243;> <UL> <LI>Regulation for Cognitive Radio <LI>Business model for dynamic spectrum access <LI>Market trend for secondary spectrum usage </LI></UL></TD> <TD style=&#8243;WIDTH: 45%&#8243;> <UL> <LI>Industrial role for dynamic spectrum access <LI>Trust and security mechanisms <LI>Game theory for dynamic spectrum access </LI></UL></TD></TR></TBODY></TABLE> <P> <P><STRONG>Technology Track:</STRONG><BR> <TABLE cellSpacing=0 cellPadding=5> <TBODY> <TR> <TD style=&#8243;WIDTH: 45%&#8243;> <UL> <LI>New architecture and platform for cognitive radio <LI>Spectrum sensing mechanism and protocol support <LI>Efficient and multi&#8211;resolution channel sensing algorithms <LI>Multiple access scheme for cognitive radio <LI>Synchronization and channel estimation for cognitive radio <LI>Radio resource management and dynamic spectrum sharing <LI>Cross&#8211;layer cognitive algorithms </LI></UL></TD> <TD style=&#8243;WIDTH: 45%&#8243;> <UL> <LI>Bio and AI&#8211;inspired algorithms <LI>Wireless network co&#8211;existence <LI>Ultra&#8211;Wideband cognitive radio system <LI>Beamforming and MIMO for interference avoidance <LI>Anti&#8211;jamming channel coding <LI>QoS provisioning and MAC protocols <LI>Interference metric modeling <LI>Self&#8211;organizing mesh networks and autonomic communications </LI></UL></TD></TR></TBODY></TABLE></P>
