BER Test Set in OFDM
Hi….I am simulating 16 QAM OFDM based Free Space Optical system in optisystem. I am using BER Test set to evaluate bit error rate performance. But the value of BER is changing every time. For example, at first it is showing 32.2X10^(-6) and next time it is showing zero for same system parameters…..In one more example, it is showing 0.00027 and next time it is showing 0.0017 for same system parameters. So I do not know which values should be considered…Kindly help
