Graph Theory Assisted Bit-to-Index-Combination Gray Coding for Generalized Index Modulation

Generalized index modulation (GIM) which implicitly conveys information by the activated indices is a promising technique for next-generation wireless networks. Due to the prohibitive challenge of bit-to-index combination (IC) mapping optimization, conventional GIM system obtains the bit-to-IC mappi...
