Performance analysis for M2M video transmission cooperative networks using transmit antenna selection

摘要

Due to mobile-to-mobile (M2M) communication unpredictability and difficulty in securing reliable channels, transmission of video over M2M networks is challenging. Cooperative communication and transmit antenna selection are two different techniques which can benefit from path diversity for robust video communication. In this paper, the outage probability (OP) performance of multi-relay-based M2M video transmission networks with transmit antenna selection over N-Nakagami fading channels is investigated. The exact closed-form expressions for OP of optimal and suboptimal TAS schemes are derived. The power allocation problem is formulated for performance optimization. Then the OP performance under different conditions is evaluated through numerical simulations to verify the analysis. The simulation results showed that the power-allocation parameter has a significant effect on the OP performance.
