What are the main block for modulation and demodulation of PSK?

PSK demodulation is used to demodulate the signal and detect the transmitted signal. The demodulation process can be divided into four major subsections such as carrier recovery, timing recovery, channel filter and data sampler as shown in Figure 2.

What is BPSK modulation and demodulation?

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 formula of PSK modulation?

In PSK modulation i(t) and q(t) have the same amplitude and indicate a phase ϕ of the modulated carrier so that i(t)=cos[ϕ(t)] and q(t)=sin[ϕ(t)].

What is 8 point phase-shift keying 8 PSK?

This is a modulation technique in which the carrier can exist in one of eight different states. As such, each state can represent three bits – 000 through to 111. This modulation technique is used in EDGE (Enhanced Data rates for Global Evolution).
