I have several channels from where I am reading sensor signals in time domain.
I have 9 channels where I am reading time domain signals from each and every channel for 10 seconds.
Now if I perform cpsd on all the channels I would get one final frequency domain spectrum lets call this as cpsd_final.
But if I am doing it like taking cpsd of 3 channels, then I will have 3 cross power spectral density matrix.
- cpsd1 - cpsd of channels 1,2,3
- cpsd2 - cpsd of channels 4,5,6
- cpsd3 - cpsd of channels 7,8,9
If I want to calculate final cpsd how can I get cpsd_final from cpsd1, cpsd2 and cpsd3?
