bit error rate

hi everbody
please..
what is the formula of the bit error rate (BER) for the following modulation schemes
QPSK, GMSK(Gaussian minimum shift keying), DPSK…
i know that the BER of the QPSK is defined as BER = (pi/2^0.5)*exp(-Eb/N)
which is related to the energy bit per noise ratio … i wish the other formulas are also relted to (Eb/n).
thank you all…
