Relationship between the BER and the data rate?

Relationship between the BER and the data rate?
  1. What is the relation between BER and SNR?
  2. How are bit error rate BER bandwidth and signal to noise ratio SNR related with each other?
  3. How does the BER generally change with SNR explain this trend?

What is the relation between BER and SNR?

SNR is logarithmic ratio of received signal and noise power, while BER is the measure of incorrect bit identification probability.

How are bit error rate BER bandwidth and signal to noise ratio SNR related with each other?

– Bit error rate is related to SNR. Higher SNR means lower BER. – Bit error rate is also related to #bits/symbol. More #bits/symbol increases bit rate, but also increases BER.

How does the BER generally change with SNR explain this trend?

There is inverse relation between SNR (Signal to Noise Ratio) and BER (Bit Error Rate). When BER is increases the SNR decrees and When BER deceases the SNR increases.
