“…In this paper, we extend our previous work [13] and propose a joint shaping technique for low-resolution optical transmission, which is experimentally verified in both intensity-modulation direct-detection (IM/DD) and coherent optical systems. More numerical and experimental results are also presented to give a deep analysis on the joint shaping technique.…”

In this paper, we propose and experimentally demonstrate a joint shaping technique to improve the performance of a lowresolution transmission system for the first time, to the best of our knowledge. The joint shaping technique combines probabilistic shaping (PS) and error feedback noise shaping (EFNS). In the 40-Gbaud intensity-modulation direct-detection (IM/DD) experimental transmission system, a bit-error-rate (BER) of 3.8 × 10 −3 can be achieved easily with the joint shaping at the physical number of bits (PNOB) of 3. In the 30-Gbaud dual polarization (DP) coherent experimental transmission system, a BER below 1 × 10 −3 is easily obtained with a 3-bit quantizer by using joint shaping. The optimization of the shaping degree is also analyzed.

“…The conventional delta-sigma converter can still obtain shaping gain when the sample per symbol (SPS) is 1.1. EFNS shows comparable performance to the DRE while also having advantages of low computational complexity, low processing delay, and no required channel response [10][11][12][13] .…”
