error on sample time in simulink

Started by domi...@gmail.com July 6, 2007
dear all,
i'm a college student that recently doing my final task about smart antenna on 802.16e standard.i'm using simulink to built my model before i generate my model code for implementing on tms320c6713.
when i run my model to verified my channel block there was one error message :
"The periodic sample time 2866005830.90379 is not allowed because the ratio of this sample time over base rate (1.786458333333333e-007) is greater than the maximum value of uint32."
for your information, i already set my simulation step size for 1.786458333333333e-007 seconds...
i don't know where the source of the error...
i would appreciate if anybody can help me with this problem....
