PSK instead FSK?

Hi,
I just started up some reading on Digital Communications. I need some
information about PSK vs FSK for use in DSP. Can anyone explain in few
words the advantages of using PSK instead FSK?

Will appreciate any help in this regard.
Thanks

In general, the BER is better for PSK over FSK.

This is not a bad read: http://www.plextek.com/papers/schmsv6.pdf
