Abstract :
The multipath is a cause of frequency notches leading to signal fading. In order to get insight into this effect the connections between individual path parameters and frequency envelope of the OFDM signal are needed. To this aim the phasor representation of the OFDM signal is proposed. The phasor representation exposes the regularity related within different paths of the signal allowing for insight into the structure of multipath OFDM channel. In this work we analyze paths with time delays also accessing OFDM symbol guard interval.
