- G. Caire, G. Taricco, and E. Biglieri, Bit-interleaved coded modulation, 1998
The foundational BICM paper — the central CommIT contribution of this chapter. Introduces the parallel-bit-channel model, derives $C_{\rm BICM} = \sum_\ell I(Y; B_\ell)$ with a mismatched-decoding converse, proves Gray labelling is near-optimal on AWGN (numerical tables in §V.B), and analyses the diversity order on fading channels in §IV. Required reading.
- E. Zehavi, 8-PSK trellis codes for a Rayleigh channel, 1992
The BICM precursor. Zehavi proposed bit-interleaving a binary code before 8-PSK mapping to break up the trellis structure of TCM on fading channels. No capacity analysis; six years later Caire-Taricco-Biglieri provided the theoretical foundation.
- A. Guillén i Fàbregas, A. Martinez, and G. Caire, Bit-interleaved coded modulation, 2008
Book-length expansion of the 1998 paper. Chapters 3 and 4 rework the BICM capacity formula rigorously via mismatched decoding and the generalised mutual information (GMI). Chapter 5 treats error exponents, Chapter 6 iterative decoding. Essential companion to the 1998 paper; our Chapter 7 of this book follows its GMI treatment.

The set-partitioning principle used throughout this chapter (Definition <a href="#def-sp-labelling" class="ferkans-ref" title="Definition: Set-Partition (Ungerboeck) Labelling" data-ref-type="definition"><span class="ferkans-ref-badge">D</span>Set-Partition (Ungerboeck) Labelling</a>). Ungerboeck's TCM is the monolithic alternative BICM replaces.
- G. D. Forney Jr. and G. Ungerboeck, Modulation and coding for linear Gaussian channels, 1998
Definitive survey of coded modulation for the Gaussian channel. §IV.D discusses BICM and its capacity, with a careful comparison to MLC. Excellent companion reading to this chapter.
- T. J. Richardson and R. L. Urbanke, Modern Coding Theory, Cambridge University Press, 2008
The standard reference on capacity-approaching binary codes (LDPC, turbo, polar). §4 covers density evolution; §6 applies LDPC to BICM on memoryless channels. The specific design recipe we assume for the binary code in the chapter's examples.
