Two-path channel

    Start To launch labAlive simulation applications you need a Java Runtime Environment supporting Java Web Start on your system. Here you can get more information about installing the right Java version.

The two-path channel is a simple multipath propagation environment. This broadband simulation uses a discrete-time channel model at such a high sampling rate that the transfer function can be processed from baseband up to the desired passband. Propagation paths are modeled as channel filter taps whose delays are at multiples of the sampling time.

Two-ray propagation channel
The transfer function is processed from 0 Hz to 2 GHz. The impulse response has taps at multiples of 0.25 ns.

Car at point A
The direct path ray propagates along the line-of-sight. A second ray reflects off the house and propagates to point A.
The distance between car and house is 60m. Determine the channel impulse response and transfer function at point A!
Car at point B
The vehicle moves 7.5 cm further to point B.
Determine the channel impulse response and transfer function at point B!
Car at point C
The vehicle moves 7.5 cm further to point C.
Determine the channel impulse response and transfer function at point C!
