1ı mentioned it above, which is my graduation project. The project will be explained a little more. LTE matlab model based on OFDM evaluate bit error rate according to EB/N0(dB). I added Pipeline ADC model to receiver of LTE model without ADC. Also, i analyzed bit error rate(BER) by changing MDAC gain of Pipeline ADC Stage 1. When gain was lower than 2, BER decreased. When gain was higher than 2, BER increased. This is unexpected situation. What could be the reason of this situation. I need help immediately. Solution of this problem is very important for me.
Kindly help me for this.
Thanks!
