Dear Sir, I am using a trail version of VisSim having addon comm/WLAN.Currently, i am running a common examples under WLAN '802.11a OFDM simulation example with guard interval'.When i clicked it ,it runs;but when i designed my self using the same specification mentioned in the example, it shows 'Sim step too small for selected code rate'.I have also attached the screenshot of that error.

Kindly help me to resolve the issue.

Thanks and regards, sanatan

    For 802.11a OFDM simulation you must choose a simulation base rate 4x faster than your bit rate. From the VisSim menu choose System > System Properties... and specify time step (or frequency) under the 'Range' tab.
