| Abstract(in English) | This paper analyzed the influence of errors of CSI feedback and according to spatially correlations to network performance in MU-MIMO system. The MU-MIMO system model constructed in this paper was based on block diagonalization algorithm with 16 streams were constructed, and the algorithm required the CSI feedback perfectly. Instantaneous received C/(N+I) distributions, BER performance, and channel capacity were simulated. As the results, it was confirmed that degradations of C/N were about 1~11dB and channel capacity of systems with correlation value i.i.d, 0.5, and 0.9 were about 48, 41 and 36 bit/s/Hz , respectively, when the average C/N was 20dB. It was confirmed that when the error of the CSI feedback was 10%, the degradation was 6 bit / s / Hz for i.i.d. Accordingly, further degradation occurred when there was an error in the CSI feedback. |
