Evm to ber
WebThe signals were generated by a software-defined transmitter. We conclude that for optical channels with additive Gaussian noise the EVM metric is a reliable quality measure. For nondata-aided QAM reception, BER in the range 10 -6...10 -2 can be reliably estimated from measured EVM. WebThe baseband EVM was measured using an FSQ8 vector signal analyzer from Rohde & Schwarz. While observing the EVM, the set-point control voltage was varied to find the …
