The fourth generation (4G) wireless products are expected to be based on worldwide interoperability for microwave access (WiMAX) systems. In this paper, the issue of channel estimation in the mobile WiMAX systems (IEEE 802.16e-2005) is analyzed. We study by simulation  the  use  of  the  least  square  channel estimation  algorithm  combining  with  several modulation schemes and interpolation algorithms. The aim  is  to  choose  the  most  feasible  interpolation algorithms  for  each  modulation  scheme  of  mobile WiMAX.  The  results  show  that  the  linear  and  the cubic sub-division interpolations perform the  best and they are proposed to be used in modulation schemes.
