摘要

我们提出了一种混合概率几何形状(HPGS) 8-PAM信令方案，作为适用于数据中心通信的备选方案。正确选择不同信噪比区域的HPGS 8-PAM参数使我们接近香农极限。我们证明了ldpc编码的HPGS 8-PAM方案优于概率形和均匀ldpc编码的8-PAM方案。

Hybrid Probabilistic-Geometric-Shaped 8-PAM Suitable for Data Centers’ Communication

We propose a hybrid probabilistic-geometric-shaped (HPGS) 8-PAM signaling scheme, as a candidate suitable for data centers’ communications. The properly chosen HPGS 8-PAM parameters for different SNR-regions allows us to closely approach the Shannon limit. We demonstrate that LPDC-coded HPGS 8-PAM outperforms both probabilistic-shaped and uniform LDPC-coded 8-PAM schemes.
