“…Recently, a combinatorial tool aided modulation concept, namely composition modulation (CM), was proposed in [9], in which the codewords of CM is formed by using compositions of an integer. Then, index and composition modulation (ICM) was developed in [10] to further enhance the SE by encoding information in index bits, modulated symbol bits as well as the composition bits.…”

In this paper, a novel index and composition modulation (ICM) transmission scheme, termed as grouped generalized composition and spatial modulation (G-GCSM), is proposed for massive multiple-input multiple-output (MIMO) systems. Specifically, it amalgamates the concepts of composition modulation (CM), generalized spatial modulation (GSM) and spatial multiplexing to attain high spectral efficiency (SE) and low implementation complexity. In the G-GCSM scheme, transmit antennas are divided into several groups and the GCSM transmission structure is employed independently in each group, facilitating the bit-toindex mapping issue in massive MIMO scenarios. Additionally, at the receiver side, an improved expectation propagation (EP) detector is designed for the proposed G-GCSM scheme, which exploits the inner sparsity of the transmitted vector in G-GCSM. Simulation results demonstrate the superiority of the proposed scheme over the existing GSM schemes in terms of bit error rate (BER) performance under the same SE conditions. Moreover, the proposed improved EP detector is able to provide a significant performance gain over the conventional minimummean-squared error (MMSE) detector in both determined and under-determined massive MIMO systems.

“…As seen from the figure, unlike the OFDM and OFDM-IM schemes, the proposed schemes are capable of providing a diversity gain equal to two due to the sole presence of index symbols. 20 They considerably outperform the OFDM and OFDM-IM schemes for all values of 20 Here, we call the symbols related to the N -tuples of the MDS code as index symbols, since we use the MDS code to embed information into the indices of codeword elements and they have the same minimum Hamming distance as those of the index symbols of the OFDM-IM benchmarks. SNR illustrated in the figure.…”

In this paper, we propose two novel modulation concepts based on a simple maximum distance separable (MDS) code and show that these concepts can achieve better error performance than index modulation (IM) and related schemes. In the first concept, we use amplitude and phase levels to form a simple MDS code, whereas, in the second one, in-phase and quadrature components of codeword elements are used to construct the MDS code. We depict practical schemes for using the proposed concepts with orthogonal frequency division multiplexing (OFDM). We analyze the performance in terms of the minimum Euclidean distance and bit error rate. We also show that the proposed techniques exhibit desirable properties such as efficient low-complexity detection, very simple bits-to-symbols, and symbols-to-bits mappings, and a better error performance when compared to the OFDM-IM and related schemes. More importantly, contrary to the vast majority of IM studies that focus on showing the superiority of the IM techniques against conventional modulation techniques, we show that modulation concepts based on a well-known MDS code can achieve better error performance than the IM and related schemes while exhibiting a structure as simple as these schemes.
