Abstract :
Orthogonal frequency division multiplexing (OFDM) is a very popular scheme for signaling at high data rates over the time-dispersive multipath channel. We analyze the symbol error probability of OFDM on the shadowed multipath channels, and present the numerical results using the typical millimeter-wave channel parameter values. The two-ray model is used as a multipath channel model. Two types of OFDM systems are considered: OFDM with and without the guard interval. We show that channel shadowing is a dominant factor that deteriorates the performance of OFDM and the guard interval is not a great contributor to multipath compensation
