- Adaptive Resource Allocation for Delay Differentiated Traffic in Multiuser OFDM Systems
- Most existing work on adaptive allocation of subcarriers and power in multiuser OFDM systems has focused on homogeneous traffic consisting of delay-constrained data guaranteed service or delay-tolerant data (best-effort service) only. This paper investigates the resource allocation problem in a heterogeneous multiuser OFDM system with both Delay-Constrained DC and No-Delay-Constrained...

- A Sub-Optimal Joint Subcarrier and Power Allocation Algorithm for Multiuser OFDM
- This paper investigates subcarrier and power allocation in multiuser OFDM. The aim is to maximize the overall rate while achieving proportional fairness amongst users under a total power constraint. Achieving the optimal solution is computationally demanding thereby necessitating the use of suboptimal techniques. Existing sub-optimal techniques either use fixed power...

- Blind Carrier Frequency Offset Estimation in SISO, MIMO, and Multiuser OFDM Systems
- Relying on a kurtosis-type criterion, a low-complexity blind carrier frequency offset CFO estimator is developed for orthogonal frequency-division multiplexing OFDM systems. The paper demonstrates analytically how identifiability and performance of this blind CFO estimator depend on the channel's frequency selectivity and the input distribution. The paper shows that this approach...
