|
| () |
| Abstract: |
| A novel power allocation algorithm for clustered OFDM UWB communication networks is presented. This algorithm assigns a unique power for each cluster while maximizing the total system throughput. Theoretical analysis and numerical simulations show that the proposed algorithm is of good performance and low complexity. It is promising in high speed communications. |
| Key words: OFDM UWB clustered throughput |
