In this paper, we propose two novel cooperative space shift keying media-based modulation (SSK-MBM) schemes. In the first scheme, a multiantenna source communicates with multiple relays and the destination by applying SSK-MBM, i.e., by altering the activated antenna and the on/off status of radio-frequency mirrors. Moreover, multiantenna relays have the capability of hybrid relaying, which means that the relays that correctly decode the source's signal take part in the transmission by applying the SSK-MBM technique; however, the relays that erroneously decode the source's signal amplify and forward their received signal to the destination. In the second scheme, we consider a novel cooperative SSK-MBM scheme with a hybrid relay selection in which a multiantenna source communicates with a selected relay and the destination by applying SSK-MBM. Error probability expressions for the proposed schemes are derived. Comprehensive computer simulations show that the derived analytical expressions are in agreement with the numerical results and show that the performance of hybrid relaying scheme is superior to that of the decode-and-forward as well as the amplify-and-forward techniques. It is shown that the proposed SSK-MBM systems outperform the conventional cooperative single-input multiple-output and spatial modulation systems for particularly high modulation orders and sufficient number of receive antennas at the destination.

混合中继的基于协作空间移位键控媒体的调制

在本文中，我们提出了两种新颖的协作式空间移位键控基于媒体的调制（SSK-MBM）方案。在第一种方案中，多天线源通过应用SSK-MBM，即通过更改激活的天线和射频镜的开/关状态，与多个中继站和目的地进行通信。而且，多天线中继具有混合中继的能力，这意味着通过应用SSK-MBM技术，正确解码源信号的中继将参与传输。但是，错误地对源信号进行解码的中继会放大并将其接收到的信号转发到目的地。在第二种方案中 我们考虑了一种具有混合中继选择的新型协作SSK-MBM方案，其中多天线源通过应用SSK-MBM与选定的中继和目标进行通信。推导了所提出方案的误差概率表达式。全面的计算机仿真表明，所推导的解析表达式与数值结果相符，并且表明混合中继方案的性能优于解码和转发以及放大和转发技术。结果表明，针对特别高的调制阶数和目的地有足够数量的接收天线，所提出的SSK-MBM系统优于传统的协作单输入多输出和空间调制系统。全面的计算机仿真表明，所推导的解析表达式与数值结果相符，并且表明混合中继方案的性能优于解码和转发以及放大和转发技术。结果表明，针对特别高的调制阶数和目的地有足够数量的接收天线，所提出的SSK-MBM系统优于传统的协作单输入多输出和空间调制系统。全面的计算机仿真表明，所推导的解析表达式与数值结果相符，并且表明混合中继方案的性能优于解码和转发以及放大和转发技术。结果表明，针对特别高的调制阶数和目的地有足够数量的接收天线，所提出的SSK-MBM系统优于传统的协作单输入多输出和空间调制系统。
