Abstract :
We address the impact of a too short guard interval (GI) length and time variations of the channel on the symbol error ratio (SER) of an OFDM system. Provided that the interference powers caused by these two effects are equal, their impacts on the SER of the system are also identical. Both analytical and simulation results illustrate our claim.
