Residual bit error rate
The residual bit error rate (RBER) is a receive quality metric in digital transmission, one of several used to quantify the accuracy of the received data.{{cite book|last=Smith|first=David Russell|title=Digital transmission systems|url=https://books.google.com/books?id=4IASeihofskC&q=%22residual+bit+error+rate%22&pg=PA48|year=2004|publisher=Springer|isbn=1-4020-7587-1|pages=47–48}}
Overview
In digital transmission schemes, including cellular telephony systems such as GSM, a certain percentage of received data will be detected as containing errors, and will be discarded. The likelihood that a particular bit will be detected as erroneous is the bit error rate.
The RBER characterizes the likelihood that a given bit will be erroneous but will not be detected as such{{cite book|last1=Crols|first1=Jan|last2=Steyaert|first2=Michiel|title=CMOS wireless transceiver design|url=https://books.google.com/books?id=YFj97fOjSHkC&q=rber+gsm&pg=PA108|year=1997|publisher=Springer|isbn=0-7923-9960-9}}
Applications
When digital communication systems are being designed, the maximum acceptable residual bit error rate can be used, along with other quality metrics, to calculate the minimum acceptable signal-to-noise ratio in the system. This in turn provides minimum requirements for the physical and electronic design of the transmitter and receiver.{{cite book|last1=Crols|first1=Jan|last2=Steyaert|first2=Michiel|title=CMOS wireless transceiver design|url=https://books.google.com/books?id=YFj97fOjSHkC&q=rber+gsm&pg=PA109|year=1997|publisher=Springer|isbn=0-7923-9960-9|page=109}}
