What are the key challenges in decoding NOMA signals compared to traditional Orthogonal Multiple Access (OMA) techniques?

12 February 2024 1 7K Report

Emil Björnson

I suppose you refer to power-domain NOMA, where successive interference cancellation is used. The key issue is that the successful decoding of one desired data signal becomes dependent on the successful decoding of other signals. This can result in error propagation and sensitive to how the data rates are selected to enable decoding at many places.
