Radio Resource Allocation for Non-orthogonal Multiple Access (NOMA) Relay Network

Radio Resource Allocation for Non-orthogonal Multiple Access (NOMA) Relay Network Using Matching Game

创新：
Although there are several works studying the resource allocation problem in the NOMA scheme, the majority of them focused on the multiple access system and few of them have considered the relay network.
系统：
we study the resource allocation problem for a single-cell non-orthogonal multiple access (NOMA) relay network where an OFDM amplify-and-forward (AF) relay allocates the spectrum and power resources to the source-destination (SD) pairs.
We aim to optimize the spectrum and power resource allocation to maximize the total sum-rate.

phase2:

phase3:

After receiving the signals, the destination nodes perform SIC
