User spectral efficiency: Combining spectral efficiency with user experience [PDF]
2016 IEEE International Conference on Communications (ICC), 2016 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 ...
