I am using 5G waveform and adding discret impulse i want to remove this impulse with median filter but block of median filter does not work .
any idea for filter to remove impulse noise in simulink?

Hello,
If the Median Filter block in Simulink is not working as expected for removing impulse noise in your 5G waveform, you can try using other filters that are commonly used for impulse noise removal. Here are a few alternative filters you can consider:
1.Moving Average Filter: This filter replaces each sample with the average of a window of samples around it. It can help in reducing the impact of impulse noise by smoothing out the values. You can use the "Moving Average" block in Simulink to implement this filter.
2.Adaptive Median Filter: Unlike the fixed-size Median Filter, the Adaptive Median Filter adjusts the filter window size based on the local characteristics of the signal. It can effectively remove impulse noise while preserving the details of the underlying signal. You can find custom implementations of the Adaptive Median Filter in MATLAB File Exchange or create your own using Simulink blocks.
3.Low-Pass Filter: A Low-Pass Filter attenuates high-frequency components, including impulse noise. You can choose from various low-pass filter designs, such as Butterworth, Chebyshev, or elliptic filters, depending on your specific requirements.
To implement these filters in Simulink, you can use the appropriate filter blocks available in the DSP System Toolbox or Signal Processing Toolbox. Configure the filter parameters according to your desired noise removal characteristics and connect the filter block to your 5G waveform signal.
Experiment with different filter types and parameters to find the best trade-off between removing impulse noise and preserving the desired signal content.
Hope this helps!
