This method originates from machine learning, but also offers an unconventional and efficient design approach for communication receivers. In the resulting receivers all signal processing degenerates to simple lookup operations in tables. These lookup tables are designed to maximize the relevant information. This paper presents a novel iterative Information Bottleneck receiver for block fading channels which uses iterative decision feedback for information-optimum channel estimation. Detection, channel decoding and channel estimation only use lookup tables constructed with the Information Bottleneck method. We compare the proposed receiver to conventional iterative receivers. Our findings show that the proposed Information Bottleneck receiver offers performance extremely close to that of a conventional double precision receiver. Moreover, it outperforms a fixed point receiver, even with entirely mismatched lookup tables. © 2018 IEEE.||URI:||http://hdl.handle.net/11420/2234||ISBN:||978-153867048-4||ISSN:||2165-4700||Institute:||Nachrichtentechnik E-8||Type:||InProceedings (Aufsatz / Paper einer Konferenz etc.)|
