WebA constellation diagram is a diagram that shows how the information in a digital modulation scheme such as phase shift keying (PSK) is represented in a modulated carrier. WebSuch a format is called quadrature PSK (QPSK), and its constellation diagram is shown in Fig. 7.20 A. As seen there, one can assign four possible combinations of two bits (00, 01, 10, and 11) to four values of the carrier phase in a unique fashion. As a result, the bit rate is halved with the use of the QPSK format.
