Propagation and Wireless Channel Modeling Development on Wide-Sense Vehicle-to-X Communications

Figure 4

Example of the time-varying power delay profile (average squared magnitude of impulse response) in the WSV2X channel. It can be found that the delay of the first taps varies because the Tx and Rx approach each other firstly and move away from each other later. The LOS tap experiences fading, the gap in the delay domain between strong components (clusters), and the LOS tap changes with time, and there is splitting of clusters over time as well.
