We introduce the concept of outage capacity for multiple-input multiple-output (MIMO)-orthogonal frequencydivision multiplexing (OFDM) systems in time and frequency block fading channels. We derive the outage capacity and its expression is shown to be related to the characteristic function of the capacity for the usual quasi-static MIMO fading channel case. We also compare the outage capacity with the performance of MIMO-OFDM systems employing powerful error correcting codes based on low-density parity-check codes when, due to finite frequency or time interleaving, there is only a small number of fading blocks per codeword.

Abstract
We introduce the concept of outage capacity for multiple-input multiple-output (MIMO)-orthogonal frequencydivision multiplexing (OFDM) systems in time and frequency block fading channels. We derive the outage capacity and its expression is shown to be related to the characteristic function of the capacity for the usual quasi-static MIMO fading channel case. We also compare the outage capacity with the performance of MIMO-OFDM systems employing powerful error correcting codes based on low-density parity-check codes when, due to finite frequency or time interleaving, there is only a small number of fading blocks per codeword.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
