    Function:    Comparison of the performances of the LS and the MMSE channel estimators
                 for a 64 sub carrier OFDM system based on the parameter of Mean square error
   Assumptions: The channel is assumed to be g(t)=delta(t-0.5 Ts)+delta(t-3.5 Ts)
                {Fractionally spaced}
