A multiple-input multiple-output (MIMO) communication system combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable
high data rate transmission over broadband wireless channels. Channel state information for both single-input single-output (SISO) and MIMO systems based on pilot aided arrangement is
investigated in this paper. The estimation of channel at pilot frequencies with conventional Least Square (LS) and Minimum Mean Square (MMSE) estimation algorithms is carried out
through Matlab simulation. The performance of MIMO OFDM and SISO OFDM are evaluated on the basis of Bit Error Rate (BER) and Mean Square Error (MSE) level.

说明： 这里有2组图，“1000.0.05”这一组是运行结果比较好的一组图，但是当时修改了时间间隔而没有改坐标说明，所以db1000.0.05.fig这幅图的坐标说明后来做了人工改正（应该是“time(0～250ms分成5000组,步长0.05ms”）。(Reuters, "1000.0.05" This group is running a relatively good results Reuters. But then amended the time interval and not changed coordinates Note So db1000.0.05.fig site map coordinates statement later became the artificial correction (should be "ti me (0 ~ 250ms group into 5000, 0.05 Step ").)
