Problem with FSK modulated signal in fading channel

I am trying to compare the theoretical bit error rate (BER) of FSK modulation with simulation in a fading channel. The channel data rate is set at 250 kbps and samples per symbol set at 10. In order to satisfy the condition
Sampling rate = SamplesPerSymbol X SymbolRate, >= ModulationOrder X FrequencySeparation,
the Frequency of separation is set at 18 KHz.
The fading channel sampling rate = Samples per symbol X Symbol rate
Since this is Binary FSK, the symbol rate is same as data rate (250 kbps).
However the theoretical and simulation results do not match.
Could anyone check please.
