  • Constellation shaping and geometric shaping

    Forney and Wei, "Multidimensional Constellations — Part I: Introduction, Figures of Merit, and Generalized Cross Constellations," IEEE JSAC, 1989

    Develops the theory of optimal constellation design beyond standard QAM, including multidimensional constellations and shaping gain. The concept of shaping gain (up to 1.53 dB) is central to modern coded modulation.

  • Probabilistic constellation shaping

    Bocherer, Steiner, and Schulte, "Bandwidth Efficient and Rate-Matched Low-Density Parity-Check Coded Modulation," IEEE Trans. Commun., 2015

    Modern approach to closing the shaping gap by using non-uniform symbol probabilities. Adopted in fibre-optic communications and under consideration for future wireless standards.

  • MSK and GMSK implementation

    Murota and Hirade, "GMSK Modulation for Digital Mobile Radio Telephony," IEEE Trans. Commun., 1981

    Original paper proposing GMSK for mobile radio, leading to its adoption in GSM. Contains the derivation of the Gaussian frequency pulse and spectral analysis.

  • Pulse shaping for 5G NR

    3GPP TS 38.211, "NR; Physical channels and modulation"

    The 5G NR standard specification for modulation schemes (QPSK through 256-QAM), constellation point definitions, and the spectral shaping requirements for each numerology.
