SQNR Improvement Enabled by Nonuniform DAC Output Levels for IM-DD OFDM Systems

SQNR Improvement Enabled by Nonuniform DAC Output Levels for IM-DD OFDM Systems

We propose and demonstrate via both simulation and experiment a scheme for a low-bit resolution digital-to-analog convertor (DAC) to improve the signal-to-quantification noise ratio (SQNR) of an intensity-modulated direct-detection (IM-DD) orthogonal frequency division multiplexing (OFDM) signal. In...
