Abstract
Enabled by fast-precoding DFT-S for PAPR suppression and noise-shaping technique for redistribution of quantization-noise in signal quantization with 4-bit DAC, a low-cost 100Gb/s short-haul Intra-DCI using 10G-class EML modulator and 4-bit DAC is experimentally demonstrated in this paper.
