Spectral efficiency

資料來源：Wikipedia - Spectral efficiency

Spectral efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. The link spectral efficiency of a digital communication system is measured in bit/s/Hz.

一個數位通信系統，在給定的頻寬限制下，可以傳送資料量就稱為頻譜效率，使用單位是 bit/s/Hz。舉例來說：

如果在「頻寬 1 kHz」環境下，毎秒能傳送「1 kbits」的資料，則其頻譜效率「1 bit/s/Hz」。
