Abstract :
In this paper, two cooperative communications schemes with interference management are proposed for multiuser wireless networks. The first scheme (Interference Constraint based Relay Selection (ICRS)) maximizes the received SNR while keeping the interference levels below a certain threshold, and the second scheme (General Order Relay and User Selection (GORUS)) is using channel state informations (CSIs) based resource allocation algorithm to improve the system performance. We derive exact closed form expressions of outage probability, ergodic capacity, and average bit error probability for the proposed schemes. Simulations are used to validate the analytical expressions. The results confirm the advantage of the proposed schemes in enhancing interference management and link reliability.
