Description: Digital phase modulation is also known as phase shift keying, 2DPSK is binary differential phase shift keying, is a kind of digital phase modulation. Digital phase modulation using carrier phase change to transmit digital signal, usually can be divided into it absolute phase shift ( BPSK ) and the relative phase shift ( DPSK ). Relative phase shift is the use of digital information and the adjacent symbols to determine relative carrier phase difference carrier phase. This paper mainly introduces the 2DPSK modulation and demodulation process and the use of phase selection method to achieve the process. And the principle of the key analysis, including modulation and demodulation principle, as well as in the modulation and the demodulation process utilizing principle to achieve absolute code and relative code generation.
