BER(Bit Error Rate) test and measurement

As we know BER is very important for any system and it measures the performance of the system at various signal to noise ratios. Usually it is measured at various SNR as desired by the system under designed based on various real time channel models for respective systems.

In this BER equipment, known PRBS pattern has been fed as input to the transmitter part of the source and data received at other side is looped back to the source.
To understand the concept, pls. refer Bit error rate basics➤➤.

There may be slight variation in the specification or limits for different wireless technologies/standards. But the basic fundamental is that we would like to measure number of bits received in error with respect to the total bits transmitted. The concept of BLER and DBLER has been introduced as variation to the normal BER based on the specific GSM system requirements.
Refer BER vs BLER vs DBLER➤➤.
