Binary phase shift keying is also known as
WebBinary Phase Shift Keying (BPSK) This is also called as 2-phase PSK (or) Phase Reversal Keying. In this technique, the sine wave carrier takes two phase reversals such as 0° and 180°. BPSK is basically a DSB-SC (Double Sideband Suppressed Carrier) modulation scheme, for message being the digital information. WebFor binary phase shift keying (BPSK), we transmit two different signals. If the baseband signal is a binary 0, we transmit: (4.15) and for binary 1′, we transmit: (4.16) BPSK can be considered as a form of amplitude shift keying where each nonreturn to zero (NRZ) data bit of value 0 is mapped into a −1, and each NRZ 1 is mapped into a + 1.
