(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.
