What is tapped delay line channel model?

A tapped delay line (TDL) is a delay line with at least one ``tap''. A delay-line tap extracts a signal output from somewhere within the delay line, optionally scales it, and typically sums with other taps to form a TDL output signal. A tap may be interpolating or non-interpolating.

What is TDL channel model?

Oct 18, 2021 at 14:49. 1. They are all well defined in the specification. In short, TDL is the model of taps with different delays (therefore the name Tapped Delay Line); each tap is modeled as a random variable.

What is a tap channel?

A tap in this context is just a point on the delay line corresponding to a certain delay. The signals from each tap can then be "summed" and the composite signal then represents what a real radio wave might look like as received by a receiver and when subject to multipath fading.

What is cluster delay line model?

Clustered Delay Line is a type of channel model when the received signal is composed of a number of separate delayed clusters. Each cluster contains a number of multipath components with the same delay but different Angle of Departure and Angle of Arrival.
