摘要
A resource allocation method and apparatus of a multi-relay orthogonal frequency division multiplexing system are disclosed. The resource allocation method of a multi-relay orthogonal frequency division multiplexing system includes: obtaining actual channel information; obtaining resource allocation parameters according to a mathematical optimization problem based on the actual channel information, where the resource allocation parameters include at least two of subcarrier power allocation, relay selection and subcarrier pairing, and the mathematical optimization problem is a mathematical optimization problem set for the subcarrier power allocation, relay selection and subcarrier pairing by using an end-to-end transmission rate optimization principle and based on channel information; and transmitting a signal according to the resource allocation parameters. The foregoing technical solutions optimize system performance.
