CMA Equalizer

Implements constant modulus adaptive filter on complex stream.

The error value and tap update equations (for p=2) can be found in:

Parameters

(R): Run-time adjustable

Num. taps

Number of taps in the equalizer (channel size)

Modulus (R)

Modulus of the modulated signals

Gain (R)

Gain of the update loop

Samples per symbol

Number of samples per symbol of the input signal

Example Flowgraph

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.
