Multipath Interference Characterization in Wireless Communication Systems Expert Lecture


Presented by Michael Rice, Brigham Young University, USA

• Multiple paths between transmitter and receiver

• Constructive/destructive interference

• Dramatic changes in received signal amplitude and phase as a result of small changes (l/2) in the spatial separation between a receiver and transmitter.

• For Mobile radio (cellular, PCS, etc) the channel is time-variant because motion between the transmitter and receiver results in propagation path changes.

• Terms: Rayleigh Fading, Rice Fading, Flat Fading, Frequency Selective Fading, Slow Fading, Fast Fading ….

• What do all these mean?.
