High Quality Content by WIKIPEDIA articles! Spectral efficiency, 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 a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the media access control (the channel access protocol). The link spectral efficiency of a digital communication system is measured in bit/s/Hz, or less frequently but unambiguously (bit/s)/Hz. It is the net bitrate (useful information rate excluding er...
High Quality Content by WIKIPEDIA articles! Spectral efficiency, 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 a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the media access control (the channel access protocol). The link spectral efficiency of a digital communication system is measured in bit/s/Hz, or less frequently but unambiguously (bit/s)/Hz. It is the net bitrate (useful information rate excluding error-correcting codes) or maximum throughput divided by the bandwidth in hertz of a communication channel or a data link. The modulation efficiency is the gross bitrate (including error-correcting codes) divided by the bandwidth.
