| Popis: | This paper considers the interference of imperfect successive interference cancellation operation and hardware noise in the joint transmission of coordinated multipoint cooperative non-orthogonal multiple access (NOMA) networks. Presumably, the statement is that distant user (cell-edge user) and base stations have no direct contacts. According to NOMA, each base station gives the information about the distant user and the near user to the cell center user (Near user), who then decodes the information of both users using the energy acquired by simultaneous wireless information and power transfer and passes it on to the cell edge user. To evaluate the performance of the suggested system, each user’s closed-form formula is represented in terms of outage probability. The findings indicate that the involvement of residual hardware impairments (RHIs) and imperfect successive interference cancellation (ipSIC) has led to an erroneous floor in the outage probability. It has been observed that ipSIC, RHIs, and both have a considerable detrimental effect on system performance. The analytical findings are verified using Monte Carlo simulations. |
