Now I have quadrature sensor which gives me output of 360 pulses per 1 rev.
Can you supply a data sheet for your encoder? Some encoders are specified with respect to the number of pulses on one channel. There may be 4x360 quadrature edge transitions available to read, and you could read 1440 counts per revolution. Other encoders are spec'd with the total transitions available in the rotation.
How can I get them multiplied lets say by 5 or by 10.
So initially I would like to get 1800 or 3600 pulses on the receiver side.
Please explain more about what you are trying to achieve.
The output from the encoder is related to the physical amount of movement. You can certainly multiply the output counts by any number you wish, but it is not going to generate higher resolution. Instead of counts going 1,2,3,4 they would go 10,20,30,40 but what does that gain you?
