Abstract: Multiple transmit-and-receive antennas jointly with orthogonal frequency division multiplexing (OFDM) provide a high number degrees of freedom for link adaptation according to the wireless channel condition. In this paper we analyze the impact of two different channel estimation techniques in the link adaptation of MIMO-OFDM wireless systems. We propose to add the choice of the channel estimation technique according to the redundancy and error caused by each strategy, which can be measured in terms of a degradation in the goodput of the system.
