Abstract
This paper addresses the topic of bit and power loading in coded MIMO-OFDM systems. Due to the need of designing communication systems with high spectral efficiencies, the combination of multiple antennas at transmitter and receiver with OFDM represents a promising approach. Moreover, channel knowledge at the transmitter can be exploited to adapt the transmission to the channel. While loading strategies for the uncoded case as well as the information theoretical solution are already known, the optimum scheme is still unknown for coded systems. In this paper, we compare different loading approaches for coded systems with respect to their error rate performance.
