CMA Equalizer

(DEPRECATED in 3.9 - Will be removed in a future release) - replaced by Linear_Equalizer and Adaptive_Algorithm

Implements constant modulus adaptive filter on complex stream.

The error value and tap update equations (for p=2) can be found in: D. Godard, "Self-Recovering Equalization and Carrier Tracking in Two-Dimensional Data Communication Systems", IEEE Transactions on Communications, Vol. 28, No. 11, pp. 1867 - 1875, 1980.

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
This flowgraph is taken from the Guided_Tutorial_PSK_Demodulation tutorial.
