Modulo Quantization Coding for Primitive Relay and Diamond Channels with Correlated Noises
Yuanxin Guo, Stark C. Draper, Wei Yu
This paper proposes modulo quantization (MQ) coding as a simple, structured, and low-complexity scheme for channels with primitive (i.e., noiseless digital) relay links and correla…

Soft Demapping of Spherical Codes from Cartesian Powers of PAM Constellations
Reza Rafie Borujeny, Susanna E. Rumsey, Stark C. Draper +1
For applications in concatenated coding for optical communications systems, we examine soft-demapping of short spherical codes constructed as constant-energy shells of the Cartesia…
