基于最佳中继选择的异构多媒体自适应协作分集算法
Heterogeneous multimedia adaptive cooperative diversity algorithm based on the best relay selection
摘要
Abstract
This paper presented an adaptive cooperative diversity programs to ensure the quality of multimedia services in a heterogeneous primary user transmission service (QoS),and to improve the data transfer performance of secondary users. Using the system model based on the power control so that the primary user’s average channel gain was relatively stable,and could be estimated in the second user,the resources could be saved in the feedback channel.According to the secondary user transmission interrupt probability was put forward in the process of secondary break the closed expression of probability,in meet the main users in the process of transmission required by the interrupt probability constraints,for primary and secondary users of collaboration and adaptability Rayleigh fading channels made the best relay selection adaptive cooperative diversity, secondary interruption as possible probability and diversity gain obtained.Simulation results show that the algorithm can reduce the outage probability of secondary users and improve spectrum efficiency,help to improve the data transfer performance of secondary users.关键词
