Secure Wireless Multicasting with MRC Diversity in the Neyman-Pearson Receiver

This paper focuses on the secure wireless multicasting under the employment of Neyman-Pearson receiver with maximal ratio combining (MRC) diversity technique. MRC diversity technique mitigate the fading effect significantly. The authors set the goal for the protection of the transmitted signal from wire-trapper considering the effects of the number of multicast users, number of eavesdropper, quantity of the antenna at the receiver and quantity of the antenna at the eavesdropper end. Authors derived the closed form analytical expressions for probability of non-zero secrecy multicast capacity (PNSMC) and the secure outage probability for multicasting (SOPM) to ensure security in the presence of multiple eavesdroppers. These mathematical models are useful for the realization of the effects of aforementioned parameters. The numerical results show that, the security in multicasting employing Neyman-Pearson receiver with MRC diversity technique is significantly affected by the number of multicast users, eavesdroppers and the antennas at the multicast users and eavesdroppers specially at low noise power region of eavesdropper channel.
