Abstract This paper proposes a novel modulation scheme called “In Phase and Quadrature-Filter Shape Index Modulation” (IQ-FSIM). It aims to enhance the spectral/energy efficiencies (SE/EE) while generalizing several existing modulations and index

In this paper, a generalized MIMO Spatial Multiplexing (SMX) system with a new Index Modulation (IM) domain called filter IM domain is proposed. This filter domain generalizes the time and frequency IM domains. In particular, a Filter Shape IM (FSIM)

This paper proposes a unified framework to describe the check node architectures of non-binary low-density parity-check (NB-LDPC) decoders. Forward–backward, syndrome-based, and pre-sorting approaches are first described. Then, they are hybridized
