We suggest practical methods of sharpening up the $H^\pm$ signature in the top quark decay at LHC using this idea. As a result one can carry on the charged Higgs boson search to within $\sim 20 GeV$ of the parent top quark mass over the full parameter space of the MSSM.14 pages, 4 figures available on requestHigh Energy Physics - Phenomenologytext
