Joint Resource Allocation and Interference Mitigation Techniques for Cooperative Wireless Networks

This chapter presents joint interference suppression and power allocation algorithms for DS-CDMA and MIMO networks with multiple hops and amplify-and-forward and decodeand-forward (DF) protocols. A scheme for joint allocation of power levels across the relays and linear interference suppression is proposed. We also consider another strategy for joint interference suppression and relay selection that maximizes the diversity available in the system. Simulations show that the proposed crosslayer optimization algorithms obtain significant gains in capacity and performance over existing schemes.
