f Quaternary Phase-Shift Keying. the binary input data for QPSK are combined. into groups of 2 called dibits. each symbol represents two bits. the bit rate is twice the baud rate. with two input bits, there are four possible. input conditions (00, 01, 10, and 11), thus. having four output phases scheme under nonlinear operation. This modulation scheme is the phase shift keying (PSK) modulation, exemplified by the special cases of BPSK, QPSK, OQPSK, π/4-QPSK. The specific nonlinear block is chosen to be the solid state power amplifier (SSPA) structure whose simulation model is the Rapp model. Varying transmitte used, the constraint that transitions from mark to space and vice versa must be phase continuous (glitch free) requires that the shift and keying rate be interrelated. A synchronous FSK signal which has a shift in Hertz equal to an exact integral multiple (n = 1, 2,) of the keying rate in bauds, is the most common form of coherent FSK • Phase Shift Keying (PSK): - Change phase with each symbol - More complex - robust against interference 10 t 1 0 1 t 1 0 1 t. 7 Basic Encoding Techniques Amplitude-Shift Keying • One binary digit represented by presence of carrier, at constant amplitud Phase Shift Keying: PSK . 2.
