That would be a typical usage scenario for stream tags (because the estimate can actually be "attached" to specific sample). I recommend going through [1] Chaper 1 to 5, where 5.2 explains the usage of stream tags.

Hi Marcus,

An example I can think of is let's say there's a channel estimation block followed by an equalizer block. 

Let's say the channel estimator estimates the channel by looking for a training sequence in the incoming data. Once it finds the training sequence it needs to transfer the data into the equalizer which it will through its output port. 

But how is the channel vector sent to the equalizer? Its not going to be a constant stream, it may just be a fixed vector of so and so number of taps. Is there a way to make the equalizer see this channel vector?
