Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.

Resampling MMSE filter.

The resampling ratio and mu parameters can be set with a pmt dict message. Keys are pmt symbols with the strings "resamp_ratio" and "mu" and values are pmt floats.

Parameters[edit]

(R): Run-time adjustable

Phase Shift
type: real
Resampling Ratio (R)
The Resampling Ratio is the fraction of (input_rate/output_rate). (type: real)

Example Flowgraph[edit]

In this example, the Resampling Ratio has an additional adjustment to compensate for Underruns at the transmitter. The factor = 1.0/((usrp_rate/samp_rate)*rs_ratio)
