Abstract
A transceiver employing layered modulation encodes two data layers with different levels of robustness and selectively decodes one or both of them regarding the reception conditions. Because of the inconsistency in encoding and decoding, conventional ordered successive interference cancellation (OSIC) can not be compatible. In this letter, we derive a dualistic OSIC architecture, which assigns distinct criteria for demodulation and interference cancellation (IC). The proposed system achieves a higher spectral efficiency while guaranteeing reliable communication.
