| Abstract(in English) | This paper analyzed transmission performances for multiuser MIMO system according to the number of users and spatial correlations under multipath fading environments. A downlink multiuser MIMO system models based on the block diagonalization algorithm with 4 and 16 streams were constructed. Instantaneous received C/N distributions, BER performance, and channel capacity were simulated by using the MU-MIMO system models. As the results, it was confirmed that degradations of C/N were about 3 dB and channel capacity of systems with 4 and 16 streams were about 18 and 56 bit/s/Hz, respectively, when the average C/N was 20 dB. Moreover, compared to the results of the channel capacity with spatial correlation of channel, the degradation of the channel capacity was about 10%. |
