| Abstract(in English) | The ergodic capacity of the multiple-input multiple-output (MIMO) channel is equivalent to the ensemble average of the capacity that is determined by a correlation matrix of a channel matrix on the assumption of a time-invariant sample process. An upper bound of the ergodic capacity can be obtained by replacing the correlation matrix of the channel matrix by its ensemble average. However, the upper bound has not theoretically been derived. Thus, this report investigates both a MIMO single-carrier transmission system on time-variant flat fading channels and a MIMO-OFDM system on time-invariant frequency-selective fading channels, as MIMO systems that can achieve the upper bound. Also, it analytically shows that the ergodic capacity of the MIMO-OFDM system can converge to the upper bound. For comparison with the capacity, computer simulations obtain packet throughput of those systems under the condition that fading varies within a block of an error correction code. They also show that the MIMO-OFDM system on the frequency selective fading channel can almost achieve the upper bound. |
