Hi Abdul,

To get power allocation coefficients for OFDM, you can follow these steps:

Define the parameters of your OFDM system.
Use the “ofdmmod” function to create an OFDM waveform using the defined parameters.
Use the “pwelch” function to calculate the power spectrum of the OFDM waveform.
By integrating the power spectral density over each suncarrier’s frequency range, determine the power in each subcarrier by using the “trapz” function.
Normalize the power in each suncarrier by the total power of the OFDM waveform. This gives you the power allocation coefficients for each subcarrier.

I hope the above information will be helpful in resolving your query.

Thanks,

Muskan
