WebPSK – Phase Shift Keying The phase of the output signal gets shifted depending upon the input. These are mainly of two types, namely Binary Phase Shift Keying B P S K and Quadrature Phase Shift Keying Q P S K, according to the number of phase shifts.
WebBinary Frequency -Shift Keying (BFSK) • Two binary digits represented by two different frequencies near the carrier frequency – where f 1 and f 2 are offset from carrier frequency f c by equal but opposite amounts – B = 2([f 2 – f 1]/2 + f b) • Where f b = input bit rate ( ) s t = Acos(2pf 1 t) Acos(2pf 2 t) binary 1 binary 0 Phase ... WebGaussian Minimum Shift keying (GMSK) Gaussian Minimum Shift Keying (GMSK) is a modification of MSK (i.e. CPFSK with h = 1/2). A filter used to reduce the bandwidth of a baseband pulse train prior to modulation is called a pre-modulation filter. The Gaussian pre-modulation filter smooths the phase trajectory of the

WebBinary Phase Shift Keying (BPSK): Quadrature Phase Shift Keying (QPSK): This is the phase shift keying technique, in which the sine wave carrier takes four phase reversals such as 0°, 90°, 180°, and 270°. If this kind of techniques are further extended, PSK can be done by eight or sixteen values also, depending upon the requirement.
