unfortunately the noise diode is not at the same period of the pulsar

However, it is also on when observing calibration source. So if I form a template for the noise diode intensity,

is that possible to subtract it for real data. BTW my data is in baseband format, which is the complex voltage.

If you have the baseband data, then you can fold the signal twice:

1. once at the period of the noise diode - for this fold, the pulsar will simply add to the system equivalent flux density.  In most cases, this is negligible.

2. once at the period of the pulsar - for this fold, the noise diode will add to the SEFD.  If the noise diode is a small fraction of the SEFD, then this is also not a problem.
