An efficient and flexible air interface is the necessary condi- tion to achieve the high data rate required from the next gen- eration wireless systems. Coded multi-antenna and multi- carrier techniques combined together with link resources adaptation algorithms are a practical answer to this need. The practicability of this concept, however, requires that the transmitter can perform accurate and simple evaluation of the actual link performance. This paper contributes to this issue with a novel method specifically developed to predict the link performance of bit-interleaved coded MIMO-OFDM links, which offers improved accuracy with the same degree of complexity when compared with conventional techniques. Its effectiveness is confirmed through extensive simulation results obtained over typical wireless channel environments.

Abstract
An efficient and flexible air interface is the necessary condi- tion to achieve the high data rate required from the next gen- eration wireless systems. Coded multi-antenna and multi- carrier techniques combined together with link resources adaptation algorithms are a practical answer to this need. The practicability of this concept, however, requires that the transmitter can perform accurate and simple evaluation of the actual link performance. This paper contributes to this issue with a novel method specifically developed to predict the link performance of bit-interleaved coded MIMO-OFDM links, which offers improved accuracy with the same degree of complexity when compared with conventional techniques. Its effectiveness is confirmed through extensive simulation results obtained over typical wireless channel environments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
