Differential spatial modulation uses the antenna index to transmit information, which improves the spectral efficiency, and completely bypasses any channel side information in the recommended setting. A generalized distributed multiple turbo coded-cooperative differential spatial modulation based on distributed multiple turbo code is put forward and its performances in Rayleigh fading channels is analyzed. The generalized distributed multiple turbo coded-cooperative differential spatial modulation scheme is a coded-cooperation communication scheme, in which we proposed a new joint parallel iterative decoding method. Moreover, the code matched interleaver is considered to be the best choice for the generalized multiple turbo coded-cooperative differential spatial modulation schemes, which is the key factor of turbo code. Monte Carlo simulated results show that the proposed cooperative differential spatial modulation scheme is better than the corresponding non-cooperative scheme over Rayleigh fading channels in multiple input and output communication system under the same conditions. In addition, the simulation results show that the code matched interleaver scheme gets a better diversity gain as compared to the random interleaver.

“…So that the DSM system can be applied to the environments where they are difficult to estimate CSI such as multi-channel and fast moving environments, which expand the application range of SM technology. At present, there have been extensive researches on this technology, such as the design of the unitary matrix [21] and the different schemes [22][23][24]. Low-complexity (LC) detection methods at the receiver [25][26][27] and application researches in different scenarios [28] are also studied.…”

Differential spatial modulation (DSM) is a multi-antenna differential technology with low power consumption and no demand of channel estimation. It is suitable for communication systems that have fast migration velocity and high requirements for both power consumption and complexity. However, due to the sparse structure and the requirements of differential coding, the spectral efficiency is limited. Therefore, media-based modulation (MBM) technology is introduced into differential system in this work to improve the spectral. A differential space time media-based modulation (DSTMBM) system is proposed. While retaining the inherent advantages of the DSM, the additional bits are transmitted through the radio frequency (RF) mirrors in DSTMBM. Unlike traditional DSM, the transmit antenna of DSTMBM system can be activated multiple times. In addition, a theoretical performance is derived, and a low-complexity (LC) detection algorithm is adopted. Simulation results show that the DSTMBM system has a performance advantage of about 4.5 dB at a high transmission rate compared to traditional DSM systems. Monte Carlo simulation matches the theoretical performance in a wide range. Meanwhile, the LC detection algorithm reduces the complexity by 2-3 orders of magnitude without the bit error rate (BER) performance loss.

“…Various DSM schemes have been proposed. In general, they can be classified into three categories: (1) to reduce detection complexity, e.g., [9]- [13], (2) to increase diversity order, e.g., [14]- [18], (3) to increase transmission rates, such as differential quadrature spatial modulation (DQSM) [19], rectangular DSM [20], and DSM using amplitude-phase shift keying (APSK) [21]- [23]. In this paper, we propose a novel DSM scheme with increased transmission rates.…”

Spatial modulation (SM) can transmit additional data bits by selecting antennas and avoids synchronization and interferences among antennas. Differential SM (DSM) is a noncoherent technique of SM, but it is less bandwidth efficient than SM. This paper proposes a novel DSM scheme called long-block DSM (LB-DSM), whose block is longer than the original DSM's. Each block of LB-DSM consists of two parts. One part is the block of the original DSM, and the other is similar to SM. With the aid of the latter part, the data rate of LB-DSM is higher than that of DSM. Besides, we propose bit mapping and low-complexity noncoherent maximum-likelihood detection for LB-DSM, by which LB-DSM is less complicated than DSM. In addition to higher bandwidth efficiency and lower decoding complexity, distance analysis and computer simulation results indicate that LB-DSM provides better error performance than DSM for 8PSK (eight-ary phase shift keying). Furthermore, the idea of LB-DSM is applied to generalized DSM (GDSM), which activates more than one transmit antenna each time. The resulting scheme, called long-block GDSM, offers better bandwidth efficiency and error performance than GDSM.
