Spectral efficiency: Link spectral efficiency, System spectral efficiency or area spectral efficiency & Overview

Spectral efficiency (alternatively, spectrum efficiency or bandwidth efficiency) refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the medium access control (the channel…
