Generation of Binary Phase Shift Keying (BPSK Generation) - Block Diagram of Binary Phase Shift Keying (BPSK)

Here we will understand the generation of BPSK signal. BPSK stands for Binary Phase Shift Keying. With the help of block diagram we will discuss the concept of Binary Phase Shift Keying generation.
But before discussing the generation of Binary Phase Shift Keying, we will first understand what is Phase Shift Keying (PSK).

Phase Shift Keying (PSK) Introduction

In Phase Shift Keying, the phase of the carrier wave (analog) is switched as per the input digital signal. This is analogous to Phase Modulation (PM).
As we know, in case of phase modulation, phase of the carrier wave is changed according to the instantaneous value of the modulating signal. In the same way, in phase shift keying also, the phase of the sinusoidal carrier wave is changed according to the digital input signal. So the basic difference between analogue modulation and digital modulation is based on the nature of the modulating signal (message signal).
