“…In [15], the diversity is achieved by dividing the transmit antennas into K antenna groups of the same size; then, according to channel state information (CSI), the receiver selects one group in each transmission block. In [4,16,17], transmit diversity is achieved by shifting the SSK modulation from the source to cooperating relays. SSK is applied to their spatial location and is called distributed SSK (DSSK) or cooperative SSK (CSSK).…”

“…Moreover, the modulation order, the number of the cooperating relays, and the number of the receiving antennas at the destination node are restricted to "2" in [4]. In [16,17], the source and relays are equipped with a single antenna, while multiple antennas are configured at the destination. In contrast to the system in [17], the relays in [16] apply a cyclic redundancy check (CRC) to detect errors during the first broadcast phase.…”

In contrast to the system in [17], the relays in [16] apply a cyclic redundancy check (CRC) to detect errors during the first broadcast phase. If a relay successfully decodes the source signal that coincided with its index, it transmits an unmodulated carrier; otherwise, it remains silent during the cooperating phase.…”

In this study, a distributed fashion of space shift keying as an efficient cooperative framework is proposed and studied to address the main challenges in future cellular networks by providing high energy efficiency and meeting the demand growth with the lowest complexity and the highest performance. A comprehensive mathematical analysis has been performed to find a closed form for the channel capacity of distributed space shift keying and to depict the influence of the number of distributed antennas on the achievable channel capacity. In addition, a simulation study of the error performance is presented using two detection methods: maximum-likelihood detection based on channel state information and blind detection. It was shown that as the number of cooperating relays increases, the error performance of the detectors converges, although they incur different costs and computational complexities. A comparison study in terms of error performance and capacity is applied with other cooperative spatial modulation to portray the outperformance of the system presented in this work.
