可以把jpg图片转换成obj三维网格文件，这样可以在三维形态下观察图像数据(Jpg images can be converted into three-dimensional grid obj file, so that patterns can be observed under the three-dimensional image data)

说明：  7. 单径瑞利信道中的两发一收STBC： (1) 分析误码率的理论性能，画出比特信噪比与误码率的关系曲线。 (2) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。(7. Two outgoing and one outgoing STBC in single-path Rayleigh channel: (1) analyze the theoretical performance of bit error rate and draw the curve of the relationship between bit SNR and bit error rate. (2) please design a specific navigation-assisted channel estimation method, Simulink simulation, measurement of BPSK modulation error rate performance.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn.)
