- Abstract
- Diversity and band AMC subchannels are under consideration for the OFDMA-based WRAN as in the mobile WiMAX. To select the proper subchannel type of a user according to the channel environment, we perform a fair performance comparison in WRAN environments reflecting the SNR variation on the link error prediction.
