High Speed Train

The high speed train condition for open space and tunnel are non-fading propagation channels with one tap and is a special very high mobility case as specified in 3GPP TS 36.104 V8.2.0 (2008-05).

The high speed train condition for leaky cable is a fading propagation channel with one path (tap). The Rician K factor is the ratio between the dominant signal power and the variant of other weaker signals.

Moving Propagation

The LTE Moving Propagation condition tests a receiver’s ability to adjust to changing delay conditions. The ETU200 profile uses multiple paths (taps) and is based on a 200 Hz doppler frequency.  ClosedIllustration...

where

The AWGN Only profile uses a single path with a doppler frequency of 622.653 Hz.

When you select Moving Propagation as the fader profile, Delay, Min Delay, Max Delay and Rate of Oscillation can be set in the fader path columns.
