Multi-user OFDM Subcarrier Allocation for Cognition Radio
This article presents the mathematical model of subcarrier allocation scheme combining radar system with cognitive OFDM sysetm based on three goals respectively. These optimization goals are minimal interference, maximum capacity and maximum capacity interference ratio. And we give the three allocation algorithm implemention steps; then compare their performance, including total system capacity and total interference. The results show that subcarrier allocation is a dynamic allocation scheme and we need to trade off between capacity and interference.
