Summary In this study, two novel distributed space‐time block coding based cooperative generalized spatial modulation networks are proposed, and their theoretical analyses are derived. The first network is a three‐node cooperative system, consisting of a source (S), a relay (R), and a destination (D). In this design, S sends a GSM symbol to R and D in the broadcast phase. In the relay phase, if R decodes the received signal correctly, it encodes the orthogonal counterpart of the GSM symbol, and sends it to D. If R has a decoding error, it sends a failure to S, and S realizes the R's transmission. The second network is designed with two relays. Here, S sends the GSM symbol to R1, R2, and D in the broadcast phase. In the relay phase, if both relays decode the incoming signal correctly, R1 regenerates the GSM symbol coming from S, and R2 encodes the orthogonal version of it. After encoding, both send them to D in a successive manner. If any or both relays fail, S sends the symbol of R2 in the relay phase. Theoretical and asymptotic analyses as well as simulation results are provided for both networks. It is seen that derived analytical expressions match with the simulation curves. Moreover, since we use the GSM in the proposed methods, their data rates are higher for the same number of transmit antennas. Even for the same spectral efficiency, they provide a significant diversity gain and a better error performance than the existing methods.

“…Relying on expanding index bits into the in-phase/quadrature domain, quadrature SM (QSM) was proposed to achieve the doubled length of index bits than SM in [32] and [33]. Moreover, the SM/SSK scheme was extended to the space-time domain to improve its BER performance, e.g, space-time shift keying (STSK) in [34], space-time block coded SM (STBC-SM) in [35], [36], and differential SM (DSM) in [37], [38]. It should be noted that all above SM related works only utilize the index(ices) of transmit antennas.…”

Quadrature spatial modulation (QSM) is recently proposed to increase the spectral efficiency (SE) of SM, which extends the transmitted symbols into in-phase and quadrature domains. In this paper, we propose a generalized QSM (GQSM) scheme to further increase the SE of QSM by activating more than one transmit antenna in in-phase or quadrature domain. A low-complexity detection scheme for GQSM is provided to mitigate the detection burden of the optimal maximum-likelihood (ML) detection method. An upper bounded bit error rate is analyzed to discover the system performance of GQSM. Moreover, by collaborating with the non-orthogonal multiple access (NOMA) technique, we investigate the practical application of GQSM to cooperative vehicular networks and propose the cooperative GQSM with OMA (C-OMA-GQSM) and cooperative GQSM with NOMA (C-NOMA-GQSM) schemes. Computer simulation results verify the reliability of the proposed low-complexity detection as well as the theoretical analysis, and show that GQSM outperforms QSM in the entire SNR region. The superior BER performance of the proposed C-NOMA-GQSM scheme make it a promising modulation candidate for next generation vehicular networks.

“…In [9]- [11], a joint transmission power and duration scheme is proposed to maximize the EE of DF two-way FD relay with the consideration of non-ideal power amplifier and circuit power. In [12] [13], spatial modulation (SM) has been proposed to increase the EE compared with that of the conventional multiple-input multiple-out (MIMO) technique. However, schemes in [7]- [13] are not suitable for the situation where SE is taken into account.…”

Owing to its high spectrum efficiency (SE), two-way relaying has aroused tremendous research interests. In this paper, the spectrum-energy efficiency (SE-EE) trade-off in decode-and-forward (DF) two-way multi-relay networks is studied by considering non-ideal power amplifiers and non-negligible circuit. Firstly, we consider the scenario of several relay nodes. To achieve better performance, the relay node with the highest energy efficiency (EE) is selected as the optimal one. Secondly, we design the optimal power allocation method to allocate each node with the optimal transmission power to enhance EE and SE. Finally, we evaluate the performance of our method and additionally analyze how the change of relay nodes' relative position influences the EE and SE. Simulation results show that: 1) the proposed method can achieve higher SE than optimal relay equal power allocation, random relay equal power allocation, and optimal power allocation only; 2) the proposed method can achieve higher EE than optimal relay equal power allocation, random relay equal power allocation, and optimal power allocation only; and 3) EE and SE increase at first and then decrease when relay nodes move from the middle of the source node and destination node to both ends.INDEX TERMS Decode-and-forward (DF), energy efficiency (EE), multi-relay, relay selection, spectrum efficiency (SE), two-way relay.
