1. A successive interference cancellation (“SIC”) system capable of removing at least a portion of interference signals, comprising:
a plurality of non-target decoder circuits configured to encode code blocks (“CBs”) from multiple non-target user equipments (“UEs”) via a wireless network;
a plurality of re-mapper (“RMAP”) circuits coupled to the plurality of non-target decoder circuits and configured to generate reconstructed non-target symbols based on the CBs; and
an SIC circuit coupled to the plurality of RMAP circuits and configured to remove interference signals by subtracting interference signals of the reconstructed non-target symbols from interfered signal of target symbols from a target UE.
