Based on the perfect reconstruction of the multi-band signal, a computing method of reconstruction function is described. This reconstructing multi-band signal from parallel sampling. Computing of reconstruction is turned to solving of linear equations. Then the validity of computing method is proven by example, and a result that the reconstruction function assures the least total sampling rate is derived.展开更多
