Research is all about making concealed assumptions

Some examples:

  • Screen-camera communication (aka. barcodes) where the camera can only move horizontally;
  • Wireless localization where the groundtruth of the location of the object to be localized is given as input;
  • The movement of the object to be localized, (Δx,Δy), satisfies dx>>dy;
  • Multipath profile of wireless channels is sparse;
  • Multipath profile of wireless channels is dense;
  • Paths of a wireless channel are different;
  • Changes of paths of a wireless channel are the same;
  • ......

The initial and most important step of doing research is making such assumptions and assuming they are correct;

and don't write them in the paper otherwise it will be rejected.
