STAR-RIS-NOMA Networks: An Error Performance Perspective
نویسندگان
چکیده
This letter investigates the bit error rate (BER) performance of simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) in non-orthogonal multiple access (NOMA) networks. In investigated network, a STAR-RIS serves users located on either side surface by utilizing mode switching protocol. We derive closed-form BER expressions perfect imperfect successive interference cancellation cases. Furthermore, asymptotic analyses are also conducted to provide further insights into behavior high signal-to-noise ratio region. Finally, accuracy our theoretical analysis is validated through Monte Carlo simulations. The obtained results reveal that STAR-RIS-NOMA outperforms classical NOMA system, might be promising 2.0 solution.

NOMA: An Information Theoretic Perspective
In this letter, the performance of non-orthogonal multiple access (NOMA) is investigated from an information theoretic perspective. The relationships among the capacity region of broadcast channels and two rate regions achieved by NOMA and time-division multiple access (TDMA) are illustrated first. Then, the performance of NOMA is evaluated by considering TDMA as the benchmark, where both the s...
متن کاملError Taxonomy of TOEFL iBT Writing: An Iranian Perspective
TOEFL iBT has turned recently heads to the impacts language tests can have on language learning. Since error analysis-based instruction has gained a new life with the advent of the computer analysis of the learner’s language, the researchers of this study embarked on examining a sample of integrated and independent writing tasks of 45 Iranian TOEFL iBT candidates in order to identify and classi...
متن کاملA Performance Perspective Based on Error Rate
In Algorithm-based fault tolerance (ABFT), the fault tolerance scheme is tailored to the algorithm performed. Most of the previous studies that compared various ABFT schemes considered only their error detection and correction capabilities. Some previous studies looked at the overhead in general but no previous work –as far as we know– compared different ABFT schemes considering performance as ...
متن کاملEdge Computing Aware NOMA for 5G Networks
With the fast development of Internet of things (IoT), the fifth generation (5G) wireless networks need to provide massive connectivity of IoT devices and meet the demand for low latency. To satisfy these requirements, Non-Orthogonal Multiple Access (NOMA) has been recognized as a promising solution for 5G networks to significantly improve the network capacity. In parallel with the development ...
متن کاملA Study of Translation Problems of Tourism Industry Guidebooks: An Error Analysis Perspective
This study was motivated by the researchers’ goal to unfold the quality of the English translations of Persian tourism industry texts and discover the most frequent error patterns the Iranian non-native translators have committed in such texts. Thus, the following research questions were addressed: 1) Are the English versions of Persian tourist guidebooks and multimedia compact discs provided b...
