Contribution
It provides the first experimental comparison demonstrating the performance advantage of bipolar constellations over intensity modulation with direct detection.
Findings
Bipolar constellations outperform IM by up to 1.8 dB.
Experimental validation of bipolar constellation advantages.
Enhanced achievable information rates with bipolar modulation.
Abstract
Achievable information rates of bipolar 4- and 8-ary constellations are experimentally compared to those of intensity modulation (IM) when using an oversampled direct detection receiver. The bipolar constellations gain up to 1.8 dB over their IM counterparts.
