简介
In this paper, two cooperative communications schemes with interference management are proposed for orthogonal frequency division multiple access (OFDMA) based wireless networks. The first scheme maximizes the received signal to noise ratio (SNR) while keeping the interference levels below a certain threshold, and the second scheme maximizes the received SNR with resource allocation algorithm based . We derive exact closed form expressions for the probability density function (PDF) of the SNR, outage probability, ergodic capacity, average bit error probability, and average consumed power for the proposed cooperative schemes. Simulations are used to validate the analytical results and an agreement is observed. The results confirm the advantage of the introduced schemes in enhancing interference management and in improving spectrum efficiency and link reliability.
