Construction and Performance Analysis of General Handoff Model with Four Nodes for Cooperative Communication

在三节点中继信道模型的基础上,根据协作通信和切换技术的特点尝试性地建立四节点的协作通信切换通用模型,并对通用模型进行仿真和系统性能分析。四节点的协作通信切换通用模型的系统性能在中低信噪比时明显优于传统通信切换,高信噪比时与传统通讯切换的性能差别不大。四节点的协作通信切换通用模型解决了切换技术在协作通信中的实现问题。

On the basis of the relay channel model with three nodes,the general handoff model with four nodes for cooperative communication according to the properties of cooperative communication and handoff technology is established.The simulation and performance of system are analyzed.The system performance of the general handoff model with four nodes for cooperative communication is evidently better than and similar to that of traditional communication handoff at low SNR and high SNR,respectively.The general handoff model with four nodes for cooperative communication resolves the implementation problem of handoff technology for cooperative communication.
