OFDMA Resource Allocation with Proportional Rates

Andrews, and Prof. Brian L. Evans Wireless
Networking and Communications Group, UT Austin
Orthogonal Frequency Division Multiple
Access (OFDMA) basestations allow multiple users
to transmit simultaneously on different
subcarriers during the same symbol period.
Our research is to allocate subcarriers and power
at the basestation to each user in order to
maximize sum of user data rates, subject to
constraints on total power, bit error rate, and
proportionality among user data rates.
Real-time DSP implementation is available.
Papers, simulation files, and real-time DSP
prototype are available for download at
