WebJun 25, 2024 · I have a query on relationship between Baud Rate and Bandwidth for 8-PSK. In 8-PSK as 3 bits together form a symbol, so Bandwidth = 2R/3, R is Bit Rate. As bit rate is 3 times BAUD RATE for 8-PSK, hence Bandwidth has to be = 2* (BAUD RATE) But in many places is see the below statement :::: 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.
