In the block diagram under Noise or Interference Cancellation –– Using an Adaptive Filter to Remove Noise from an Unknown System, this is . The signal is correlated with the noise that corrupts the signal data. Without the correlation between the noise data, the adapting algorithm cannot ...
A series of large input values, coupled with the quantization process might result in the error growing beyond all bounds. Restrain the tendency of the sign-data algorithm to get out of control by choosing a small step size(μ≪1)and setting the initial conditions for the algorithm to nonz...
