This book presents reduced complexity and proportional data rate fairness resource allocation schemes for next generation broadband mobile wireless communication systems. At first we present proportional data rate fairness resource allocation scheme for Multi-Input Multi-Output Orthogonal Frequency Division Multiple Access (MIMO- OFDMA) broadband mobile wireless communication system. In this scheme, users are separated in frequency domain and they cannot transmit their data in same frequency with other users at the same time. Therefore, second resource allocation considers to use the radio...
