The Resource Optimization Allocation Of Cooperative Communication

Transmission over wireless channels suffers from multi-path fading, which is the biggest problem that affects the data rate and quality of service. Relayed transmission is completed by the cooperation between source and relay. As a result, resource allocation becomes an important issue in wireless cooperative diversity networks. In this paper we first stud the user cooperative model of AF, DF optimize the allocation of power under the agreement derived BER expression and conduct simulation to validate its performance; and then extended to the distributed cooperative communication systems to research power optimization case based on opportunities relay; finally we make use of the bargaining function of the Game theory to study the collaboration communication AF, DF protocol. We get the conclusion that a cooperative power allocation based on the Game theory can effectively increases the utility of the entire system.
