description A resource reuse perfect reconstruction sub-band analyzer comprises an interpolation module, a 2m dot symbol adjusting module, an FIFO module, an N-way multiplication module, an N-way addition module, a complex multiplication module, a sub-band filter coefficient table, a complex multiplication coefficient table, a 2m dot FFT module and a perfect filter factor adjusting module. The resource reuse perfect reconstruction sub-band analyzer can conduct 2m times reuse on hardware resources, the expenditure of hardware resources is lowered, the structure is simple and universal, parameter configuration is flexible, the technological indexes such as the number of ways, the speed and the bandwidth for sub-band analysis can be rapidly changed, and the resource reuse perfect reconstruction sub-band analyzer is suitable for various bandwidths and speeds and capable of being widely applied to mobile satellite communication systems, software-based processing transponder satellite systems, ground face mobile communication systems and various data collecting systems.
