Cognitive radio enabled small cell network is an emerging technology to address the exponential increase of mobile traffic demand in next generation mobile communications. Recently, many technological issues, such as resource allocation and interference mitigation pertaining to cognitive small cell network have been studied, but most studies focus on maximizing spectral efficiency. Different from...
Cognitive radio enabled small cell network is an emerging technology to address the exponentially increasing mobile traffic demand of next generation mobile communications. Recently, many technological issues pertaining to cognitive small cell network have been studied, such as resource allocation, but most studies focus on spectral efficiency maximization. Different from the existing works, we investigate...
Cognitive radio (CR) networking achieves high utilization of the scarce spectrum resources without causing any performance degradation to the licensed users. Since the spectrum availability varies over time and space, the infrastructure-based CR networks are required to have a dynamic inter-cell spectrum sharing capability. This allows fair resource allocation as well as capacity maximization and...
