LDPC Codes with Soft Interference Cancellation for Uncoordinated Unsourced Multiple Access
LDPC Codes with Soft Interference Cancellation for Uncoordinated Unsourced Multiple Access
This article presents a novel enhancement to the random spreading based coding scheme developed by Pradhan et al. for the unsourced multiple access channel. The original coding scheme features a polar outer code in conjunction with a successive cancellation list decoder (SCLD) and a hard-input soft-output MMSE estimator. In contrast, …
