 During my research period i have analyzed the timing and spectral properties of black hole candidates (BHCs) MAXI J 1659-152 and H 1743-322 with Two Component Advective Flow (TCAF) model  using their outburst data from Rossi X-ray Timing Explorer (RXTE) satellite. We have also calculated mass of these BHCs from TCAF fits. Depending on the nature of QPO frequency and accretion rate ratio (ARR) we classify the total outburst phase of MAXI J1659-152 into three spectral states and for H 1743-322 the spectral states are classified into four spectral states.  From TCAF fitted constant normalization method we calculate mass of MAXI J 1659-152 within a range of 4.7 – 7.8 solar mass and for H 1743-322  the mass comes in the range of 9.43 – 12.71 solar mass.
