FSK adjusts the frequency, PSK adjusts the phase. We use nonstandard PSK in our work because we can design a pre-amp and amp around the one frequency and design a filter with broad Q in the range of the expected signals we are trying to extract. We don’t bother with quadrature. I am not sure if you are a beginner or not. If you are then forget about what I just said 😉 Here is a good reference with pictures.
