Hierarchical Interference Cancellation in BPSK 3-Source Multiple Access Channel with Wireless (Physical Layer) Network Coding

Popis výsledku v původním jazyce

Successive Decoding with Interference Cancellation (SD-IC) is well understood to be a capacity achieving decoding strategy in Multiple Access Channels (MAC). This decoding technique allows a consecutive elimination of interfering signals during the successive decoding of particular user data. The ability to perfectly remove the interfering signal from the subsequent decoder processing (after corresponding user?s data have been successfully decoded) relies on a one-to-one mapping between the user data sequence and its signal space representation. However, this is not always guaranteed in Wireless (Physical Layer) Network Coding (WNC) systems, where only specific (?hierarchical") functions of user data are decoded. In this paperw we analyse this particular research problem in a simple binary 3-user MAC channel, which is capable to demonstrate the issues associated with successive decoding in WNC systems. We show that a hierarchical extension of conventional SD-IC processing appears to be
