Digital matching filter with compound architecture based on matrix
Mei Dacheng · Journal of Computer Applications · 2010
Under discussion of the background of logging signal transmission based on discrete Sequence-Spread Spectrum (DS-SS) technology,the research and design of a compound architecture Digital Matching Filter (DMF),configured on FPGA,was described in detail.In this filter,the matching filtering progress was made by recursive matrix operations,and common multi-multiplier adder frame was replaced by a way of look-up table value finding,to ensure the well site requirements of simple instrument structure and work efficiency.The testing results show that the processing effects done by the filter meets the design requirements.
