The paper focuses on improving wireless communication networks for nuclear radiation monitoring by analyzing and evaluating the performance of Multi Carrier Code Division Multiple Access (MC-CDMA) as a wireless communication system. The work aims to determine the outage probability as a quality-of-service parameter and investigate the average channel capacity under channel deterioration. They use closed form expressions to present the performances of these characteristics and study the impact of the number of branches and subcarriers on the outage probability. In addition, the authors propose a robust and reliable approach to channel under fading and study the capacity of MC-CDMA with the largest number of users. The results obtained from the study confirm that exponential channel fading achieves the lowest outage probability compared to other channel degradations. Moreover, the proposed results guarantee high average channel capacity and high throughput, which are essential for the successful deployment of MC-CDMA systems. The findings of this study provide valuable information for researchers and engineers working in the field of wireless communication systems, particularly those interested in the design and optimization of MC-CDMA systems. Overall, the paper contributes to the understanding of the performance of MC-CDMA systems under various channel conditions and provides insights into the design and optimization of such systems. The results show that the importance of utilizing robust and reliable wireless communication systems in nuclear radiation monitoring to ensure the accuracy and reliability of the data obtained.
