摘要

Next-generation wireless communication requires significant investment and collaborative research to address fundamental challenges. Cooperative communication is crucial in this context, enabling improvements in reliability, throughput, and outage performance. This paper presents a performance analysis of multiple-antenna incremental relaying decode-and-forward (MA-IR-DF) assisted simultaneous wireless information and power transfer cognitive radio-inspired non-orthogonal multiple access (SWIPT-CR-NOMA) system with a singular value decomposition (SVD) scheme. The network architecture comprises four key nodes: primary transmitter (PT), primary user (PU), secondary transmitter (ST), and secondary user (SU), interconnected through multiple links. During the initial phase, PT transmits the primary signal, which is received by PU and ST. Upon successful decoding, ST combines the primary signal with its own secondary signal, and the combined signal is then forwarded to PU and SU, respectively, in the subsequent phase. We investigate the system’s performance over Rayleigh fading channels, deriving closed-form expressions for outage probability, system throughput, ergodic capacity, and energy efficiency. The analytical and simulation results demonstrate the superiority of the proposed MA-IR-DF-assisted SWIPT CR-NOMA system with SVD scheme over traditional systems.
