摘要

This paper presents a novel approach to cooperative non orthogonal multiple access (NOMA) using distributed space time block coding (STEG) known as STEG-NOMA. In conventional NOMA, the strong users detect the messages of weak users through successive interference cancellation (SIG). In cooperative NOMA, these copies are then forwarded by strong users to weak users at the expense of extra time slots. However, the proposed scheme exploits this feature of cooperation using STEGs to enable cooperation among the users. The STEGNOMA renders less complexity as lesser number of SIGs are performed at each user. To this end, we derive the outage probability of the STEG-NOMA scheme which involves finding the distribution of signal-to-interference ratio at the receiving terminals. The numerical results show that STEG-NOMA outperforms conventional NOMA and conventional cooperative NOMA in terms of outage probability and average sum rate.
