Generalised vector precoding design based on the MBER criterion for multiuser transmission
, 2010 A generalised vector precoding (VP) design based on the minimum bit error rate (MBER) criterion is proposed for multiuser transmission in the downlink of a multiuser system where the base station (BS) equipped with multiple transmit antennas communicates

Error vector magnitude relation to magnitude andphase distortionin 8-PSK systems
Electronics Letters, 2001 Distortion in 8-PSK systems is a consequence of magnitude and phase disturbances. This work investigates the effects of such distortions (either isolated or combined) due to Gaussian bandpass noise, through analytical and simulation studies. Analytical expressions are derived and analytical-based results, relating error vector magnitude to symbol error

Linear Regression vs. Deep Learning for Signal Quality Monitoring in Coherent Optical Systems
IEEE Photonics Journal, 2022 Error vector magnitude (EVM) is a metric for assessing the quality of m-ary quadrature amplitude modulation (mQAM) signals. Recently proposed deep learning techniques, e.g., feedforward neural networks (FFNNs) -based EVM estimation scheme leverage fast ...
