Offset QPSK, π/4-QPSK, and minimum shift keying are modulation schemes that mitigate the effects of high-slope symbol-to-symbol voltage changes. Differential QPSK uses the phase difference between adjacent symbols to avoid problems associated with a lack of phase synchronization between the transmitter and receiver.
了解详细信息：Offset QPSK, π/4-QPSK, and minimum shift keying are modulation schemes that mitigate the effects of high-slope symbol-to-symbol voltage changes. Differential QPSK uses the phase difference between adjacent symbols to avoid problems associated with a lack of phase synchronization between the transmitter and receiver.

www.gaussianwaves.com/2010/04/performance-co…Spectral Efficiency of BPSK Let S p(f) be the PSD of BPSK and let S(f) be the PSD of its complex envelope. S p(f) = S(f f c) + S( f f c) 2 (Section 2.3.1 of Madhow’s book) The complex envelope is given by s(t) = X1 n=1 b np(t nT) where p(t) is a rectangular pulse of duration T and b n 2f A;Ag.

The most straightforward type of PSK is called binary phase shift keying (BPSK), where “binary” refers to the use of two phase offsets (one for logic high, one for logic low). We can intuitively recognize that the system will be more robust if there is greater separation between these two phases—of course it would be difficult … 展开
