Abstract
This paper assesses the spectral efficiencies that can be achieved in theory and simulation for several channel models, and where the same spectral efficiencies can result from different combinations of the signal constellation and channel code rate. A trade-off analysis is presented both for satellite and terrestrial channels for the impact on the spectral efficiency Γ of increasing the modulation order and at the same time reducing the code rate.
