Abstract

The authors discuss the problems related to a proper definition and evaluation of spectral efficiency in order to find out which aspects are relevant for comparison among different solutions, and which aspects determine only the final absolute value. In particular, it is shown that different coverage strategies and propagation conditions not only affect the absolute value of spectral efficiency but also the comparison among different systems. The concept of a `scenario´ for evaluation and comparison is introduced, and examples of computation of spectral efficiency are given in a deterministic and in a statistical scenario (in the presence of log-normal fading). A reference optimum system is introduced in order to be able to express system spectral efficiency in a relative way
