Multiobjective joint optimization and frequency diversity for efficient utilization of the RF transmission hyperspace

This paper discusses a new approach for the spectrum management of RF radio communications and sensor devices that enables 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. Currently, there are no known technological approaches to RF transmission in spectrum management that consider all of these dimensions jointly, and certainly none that consider them in the context of a system optimization problem. This paper describes the various aspects of the multi-dimensional transmission hyperspace and approaches for efficient spectrum management, including the application of frequency diversity techniques, the results of which are expected to garner several orders of magnitude improvement in RF resource utilization and therefore, aggregate information throughput.
