Modulation Error Ratio

Modulation Error Ratio. Modulation Error Ratio (MER) Communications Toolbox™ can perform Modulation Error Ratio (MER) measurements MER is a measure of the signaltonoise ratio (SNR) in a digital modulation applications These types of measurements are useful for determining system performance in communications applications.

IntroductionMer TestingConclusionMER is known as Modulation Error Ratio In simple words MER is errors detected in modulation between what we transmitted and what we received MER is measured in dB We face a problem generally in cable tv industry that all the channels of all Transport Streams are working fine in headend but in the field we are getting free.

For the purpose of this project work a symbol error ratio (SER) or a bit error ratio (BER) was measured/calculated for a various values of signal to (noise + interference) ratios S/(N + I) where noise = additive white Gaussian noise (AWGN) and interference =.
