Radio Resource Allocation in Wireless OFDM Systems
In this thesis, we study radio resource allocation problems in wireless OFDM systems using both centralized optimization and game theoretic approaches. In our work we consider only integer numbers for bit-loading for practical purpose. The subcarrier, bit and power allocation (SBPA) problem in …
