sir can u please tell something about spectral analysis of ofdm in matlab???

Mahbubur Rahman Vlogson January 22, 2022 at 5:26 pm

Hi, Currently, I am using FM Broadcast Radio example in Simulink that came with Matlab by default. In that example, I modified by adding a spectrum analyzer where I want to see the power of the signal in dBm. Now I want to add a block which will create .xls file to record the power of a signal at a particular frequency. For example, If I choose to listen to FM radio at 102.5MHz, thus the data recorder should record the power of the center frequency at 102.5MHz. could you please suggest how can I do?

can U help me with the code used in the video…i can’t find it on the internet ….. help me with some link or something…….email id is jashbhensdadia@gmail.com

This is one of the best tutorials I have watched. It is well explained and easy to follow. Thank you for sharing!

I want to use spectrogram for short time fourier based power system DC current Fault analysis. i have to questions:
– how can I plot specific frequencies (ex. 14th frequency) by time after using spectrogram?
-How can I change x and y axis units? the x time axis shows 1 to 10 minutes but my signal is ni 1 milisecons, my y axis should be in hz but it is normalized

If we are finding the periodicity then how can we make confidence interval to check whethr the peaks are significant or not??

holaaaaa

Wendy Fernandezon January 22, 2022 at 5:37 pm

I would like to know if there is a way to do a spectrogram with frequency in the x-axis and amplitude in the y-axis? In addition, besides the spectrogram, what other visualization functions can be used to analyze signals in the frequency domain, i.e. 3D plots?

Hallo everyone. Can i help you? I want to ask How to analyze The data of wave and tides with take the advantages FFT method on Matlab program. Matlab program which is function in time domain and it can transformed in frequency domain and output in chart form.
Thank you.

I have never come across such wonderful video. Thankyou. It’s very useful! Can you do a video on TDNN (Time Delay Neural Network)? Or RNN for signal denoising using MATLAB?

Hello.
How can you know for a random signal (respiration signal example)
where are the frequency components, i’ve seen that in all the examples, you already know where are the frequency components.
thanks

RamsesN Non January 22, 2022 at 5:51 pm

Is there a way to normalize the power of the frequencies in the spectrogram function? and shown them normalized in the spectrogram?

keerthi c.jon January 22, 2022 at 5:51 pm

Could you please add the description of the same program

Xin Tianon January 22, 2022 at 5:54 pm

Does anyone know how to automatically find the peaks in the spectrum? I find his code SpecDemoHelper1&2 but they are for demo and the peaks are found manually(I guess)?
Any comment will be appreciated!

Hi, i am Vicki

Right now i am learning matlab, but i am just begginer at matlab, right now i want to learn about how to using low and high pass filter, Savitzky-Golay Filtering (SGOLAYFILT), mean and varians, and also find out the peak and valley point from the gyro and accelerometer signal, and all my data i get from excel.

can You give me some tutorial or code how to make it

I really hope You can help me to figure it out.

Best Regards
Vicki
