Résumé:
Resource allocation for an uplink cooperative
OFDMA system is considered in this paper. Relays are simple
mobile users with advantageous positions to relay other users
with bad channel conditions. Having their own data to transmit
to the Base Station (BS), the relays multiplex their own data
to relayed data before transmitting to BS using Decode and
Forward (DF) scheme. The resource allocation is formulated
as an optimization problem to minimize the transmit system
power while ensuring a target data rate per user. The considered
features to optimize are relay selection, power and Resource
Blocks (RB) allocation. Dual decomposition is used for resolution.
Both half and full-duplex users cases are studied and compared
to non-cooperative system. Simulation results show that our
proposed algorithm reduces system’s power consumption while
ensuring required QoS.
