Leveraging communication performance for OFDMA using novel bit loading and allocation of power

In the modern communication system, though there is up gradation of resource availability yet radio resources are in constraints situation due to high data transfer requirement of multimedia traffic in the presence of advanced antenna. There is a need of resource utilization framework, which balances the tradeoff of high dimension data with optimal quality using joint allocation methodology for power allocation and bit loading. The encoding mechanism induced at layer level is having differentiated priority. This paper proposes a scheme of packet prioritization for achieving maximum utility under fixed rate constraints. Further, a joint power allocation and bit loading mechanism are conceptualized on OFDM access using clustering of users, power adaption and bit loading. The validation of the model is done by evaluating its performance with traditional resource allocation methods.
