User spectral efficiency: Combining spectral efficiency with user experience [PDF]
Electromagnetic spectrum is a scarce resource. Spectrum licensing is estimated to consume about 20% of cellular operators' capital expenditure (CAPEX). One important measure of spectrum use is “spectral efficiency” (SE), which is the amount of data bandwidth that a specific technology can extract from a certain amount of radio spectrum and is measured ...

Spectral efficiency of blackness induction [PDF]
The spectral efficiency of blackness induction was measured in three normal trichromatic observers and in one deuteranomalous observer. The psychophysical task was to adjust the radiance of a monochromatic 60-120' annulus until a 45' central broadband field just turned black and its contour became indiscriminable from a dark surrounding gap that ...

Binary CPMs With Improved Spectral Efficiency [PDF]
We design new continuous phase modulation (CPM) formats which are based on the combination of a proper precoder with binary input and a ternary CPM. The proposed precoder constrains the signal phase evolution in order to increase the minimum Euclidean distance, and to limit the bandwidth expansion due to the use of a ternary CPM.

Spectral efficiency of energy efficient multicarrier systems [PDF]
We investigate the achievable performances of multi-carrier energy efficient power control game. Both the simultaneous-move and the hierarchical games are addressed. For the first time, we derive analytical closed-form expressions of the spectrum coordination and the spectral efficiency of such models.
