As shown in the figure-1, two bits are mapped to one symbol in QPSK. This will reduce the bandwidth to half in comparison with BPSK modulation. In BPSK, one bit is mapped to one symbol. Before mapping, binary data stream is converted from serial to parallel so that two bits are incident simultaneously to two mixer inputs. employer support of immigration application

Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave). The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and … See more There are three major classes of digital modulation techniques used for transmission of digitally represented data: • Amplitude-shift keying (ASK) • Frequency-shift keying (FSK) See more Sometimes this is known as quadriphase PSK, 4-PSK, or 4-QAM. (Although the root concepts of QPSK and 4-QAM are different, the resulting modulated radio waves are exactly the same.)
