Resource allocation in uplink wireless multi-cell OFDMA networks
We propose deterministic and stochastic models for wireless OFDMA networks. We maximize signal to interference noise ratio and total capacity of the system. We derive equivalent mixed integer programs and piecewise linear approximations. We propose a meta-heuristic procedure to obtain near optimal solutions. The numerical results are obtained in significantly less computational cost.
