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.[1]

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[2]

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.[3]
