New NOMA power allocation strategy

open access: yesTongxin xuebao, 2017
Non-orthogonal multiple access(NOMA) has been widely used in the research of the fifth generation communication,due to the advantages of improving the spectrum efficiency and data rate.In order to guarantee the service of users,a new power allocation ...

A Resource Allocation Scbeme Based on User's QoS in MIMO Relay System

open access: yesDianxin kexue, 2015
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 ...

Resource allocation scheme in two-way multi-relay OFDM system

open access: yesTongxin xuebao, 2017
A joint optimization scheme for power allocation and subcarrier pairing under high SNR in two-way multi-relay OFDM system was proposed.Unlike those schemes in which relays use subcarriers separately,all the relays were allowed to forward signal on each ...
