Multiuser OFDM with adaptive subcarrier, bit, and power allocation.

Multiuser OFDM with adaptive subcarrier, bit, and power allocation.

Multiuser orthogonal frequency division multiplexing (OFDM) with adaptive multiuser subcarrier allocation and adaptive modulation is considered. Assuming knowledge of the instantaneous channel gains for all users, we propose a multiuser OFDM subcarrier, bit, and power allocation algorithm to minimiz...
