Comparison of Receiver/Transmitter Algorithms for OFDMA with Dynamic Subcarrier Allocation

Authors: C. Bockelmann, M. Petermann, K.-D. Kammeyer
Abstract: We consider the downlink of a multiuser MIMO-OFDMA system with different transmitter and receiver concepts, where subcarriers are assigned to users according to some metric. This metric describes the channel quality and the user with the highest metric at a subcarrier is allowed to transmit. The examined transmission schemes are shown to behave differently based on the chosen metric. Furthermore, the influence of channel coding on this behavior is investigated.
