We analyze the influence of DGD on beyond 200-Gb/s PAM-4 transmissions. We find the precoding and a joint PRE with MLSE have a better DGD tolerance among various equalizers, achieving 1.9-dB gain ...

In this paper wideband beamforming in near-field uniform planar array (UPA) systems are studied. Growing communication frequencies in the next-generation communication systems require ...
