Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
passive quantization » adaptive quantization
modified passive » modified adaptive
using real » using metal
using raw » using a, using low, using rbf

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive quantization algorithm ) or ( code ((using real) OR (using raw)) algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive quantization algorithm ) OR ( code ((using real) OR (using raw)) algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive quantization algorithm ) or ( code ((using real) OR (using raw)) algorithm ))*".
