Modulation Error Ratio (MER)
Communications Toolbox™ can perform Modulation Error Ratio (MER) measurements. MER is a measure of the signal-to-noise ratio (SNR) in a digital modulation applications. These types of measurements are useful for determining system performance in communications applications. For example, determining if an EDGE system conforms to the 3GPP radio transmission standards requires accurate RMS, EVM, Peak EVM, and 95th percentile for the EVM measurements.
As defined by the DVB standard, the unit of measure for MER is decibels (dB). For
consistency, the unit of measure for Minimum MER and Percentile MER measurements is also
in decibels. For more information, see the
comm.MER help page.
