New approaches for enhancing spectrum utilization and frequency management for large, complex systems have recently been investigated. These approaches enable the effective and efficient joint utilization of all orthogonal electromagnetic (EM) transmission resources, including, but not limited to time, frequency, geographic space, modulation/code, and polarization. This multi-dimensional environment is hereafter referred to as the Transmission Hyperspace (TH), a term intended to convey the notion of a multi-dimensional resource space (with n degrees of freedom expressed as an n-tuple) in which each dimension allows orthogonality amongst users. The challenges to the modeling and solution of large-scale TH-based problems are presented in the context of assigning the n-tuple dimensions in near real time. Also described are the key aspects of the multi-dimensional Transmission Hyperspace and approaches for efficient spectrum management, the results of which are expected to garner several orders of magnitude improvement in RF resource utilization and therefore, aggregate information throughput.
