摘要：
This work deals with a power and bit allocation algorithm applied to MIMO-OFDM systems. Particularly, the V-BLAST transceiver structure is envisaged as a potential candidate for such approach. Simulation results show that the clever allocation of resources (power and transmission modes) in accordance to the channel represents a great improvement in the performance of the system in terms of goodput.
