BER in scatter plot

I have small question regarding BER in scatterplot. I plotted a scatter plot as shown below, but in that plot how can I determine BER?,

Hi Darshan,

BER is not releated to complex symbols. So, it can'e be known from scatter plot.

You need to first demodulate the symbols to bits and then calculate the bit error rate, by calculating error when compared with transmitted bits.

To compute BER, you can use biterr function.

Hope this helps.
