gfd

RCFD has similar performance as GFD, while it costs less in realization, because it realize the time match filter and frequency match filter in one structure.

该结构中的FD采用了RCFD，它与传统的GFD相比有着类似的性能，而且通过在时域匹配滤波器的结构上衍生出频域匹配滤波器结构，大大节省了实现开销；

The research of conservation difference schemes and high fidelity model design is recounted and the related remark about the GFD numerical model approaching is presented in this paper.
