Two effective allocation schemes are proposed for Multiuser MIMO-OFDM systems with zero-forcing beamforming. Through adaptive power,subacarrier and bit allocation, our objective is to minimize the total transmit power while satisfying the target data rates of all users. The numerical results show that the two proposed sub-optimal methods can achieve good performance while satisfying the rate demand of users.
Key words： MIMO-OFDM; adaptive resource allocation; transmit power
