VC-This is an acoustic-driven touch screen positioning of the source calibration procedure.
这是一个声波触摸屏驱动中的定位校准程序的源码。
Under the constraint of DOA angles and sensor gains in the signal subspace, the estimation of sensor gain can be obtained without any calibration source.
运用信号子空间对信号DOA和通道增益的约束关系，在无校准源时，可以得到通道增益的估计。
This method needs only one calibration source. Its calibration effect is good, and the calibration performance is stable.
该方法只要一个校准源，校正效果好，性能稳定，所需运算量也不大。
