WebThe three closely running curves below correspond to PSK, coherent and non-coherent diﬀerential PSK (DPSK), respectively. For the coherent DPSK SNR bit,BER=10−5 = 9.76 and for the non-coherent DPSK SNR bit,BER=10−5 = 10.82, [11]. There is no signiﬁcant diﬀerence between these three curves, i.e., DPSK is only slightly inferior to PSK.
