A Resource Allocation Scbeme Based on User's QoS in MIMO Relay System
For the resource allocation in OFDMA MIMO relay downlink system,a quality of service aware resource allocation scheme with low complexity under total power constraint was proposed.First,under the assumption of equal power allocation,a selective priority factor was chosen for the relay selecting and...

| description | For the resource allocation in OFDMA MIMO relay downlink system,a quality of service aware resource allocation scheme with low complexity under total power constraint was proposed.First,under the assumption of equal power allocation,a selective priority factor was chosen for the relay selecting and subcarrier allocation.The relay selection and subcarriers allocation were carried out depending on the priority factor.Then the optimal power allocation was implemented through convex optimization algorithm.Numerical results show that the proposed scheme can not only achieve the higher capacity of system,but also guarantee the quality of service for each user. |
