What type of receiver is used for BPSK detection?
Coherent correlation receiver for BPSK. The coherent receivers for QPSK, OQPSK, and MSK are of the form shown in Fig. 15. These receivers consist of two branches, and each branch is a correlation receiver for an appropriate binary signal.
What is BPSK transmitter?
Binary Phase-shift keying (BPSK) is a digital modulation scheme that conveys data by changing, or modulating, two different phases of a reference signal (the carrier wave). The constellation points chosen are usually positioned with uniform angular spacing around a circle.
What is the working principle of BPSK?
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. The resulting signal is then passed through a filter to limit its bandwidth and then multiplied by the carrier signal cos ωt (see Figure 4.2).
