Ergodic capacity of opportunistic non-orthogonal forward protocol over Rayleigh fading channel
摘要
Abstract
To obtain the ergodic capacity of opportunistic non-orthogonal amplify-and-forward forward protocol and opportunistic non-orthogonal decode-and-forward protocol over Rayleigh fading channels,the closed expressions for the ergodic capacities under the two protocols were deduced,and the values of the ergodic capacity was given through Monte-Carlo simulation.The results show that the ergodic capacity's values of the two protocols will improve along with relay node number increasing,and the improvement tendency will hasten delay when the relay node number arrives to a certain value.The opportunistic non-orthogonal amplify-and-forward forward protocols could obtain a larger ergodic capacity value at lower SNR(signal noise ratio),while the opportunistic non-orthogonal decode-and-forward protocol has a better ergodic capacity performance at higher SNR.关键词
