What is Block Error Rate?
The Block Error Rate (BLER) is a quantitative measure of how well audio is retained on a compact disc (CD) over a period of time. It is used to measure the error rate at the time of extracting frames of data from a CD. The BLER is the ratio of total bad blocks to that of the total number of blocks that are received in a digital circuit.
The block error rate is also referred to as the block error rate.
According to the European Telecommunications Standards Institute (ETSI), 'A Block Error Ratio' is defined as the ratio of the number of incorrect blocks received to the total number of blocks sent. A faulty block is defined as a transport block whose cyclic redundancy check (CRC) is incorrect. ‚
Therefore, the BLER can be determined using the following formula:
BLER = EB ÷ TB
BLER = block error rate
EB = error blocks
TB = total blocks
The best-known application of BLER is found in industries that use LTE / 4G technology, such as the telecommunications industry. The main purpose of using the BLER in the telecommunications industry is to determine the synchronized or unsynchronized indication at the time the radio link monitoring (RLM) is performed. As an industry standard, 2 percent is considered a normal synchronous state, while 10 percent is considered out of sync. Typically, BLER is measured after channel decoding and after performing the cyclical redundancy check (CRC) for all transport blocks after deinterleaving.
