Abstract: PHASE SHIFT KEYING dPSK wireline modems. These modems utilize frequency shift keying (FSK), phase shift keying (PSK), and , phase shift keying (DPSK). ITU PSK modems typically use symbol sizes from 2 to 4 bits (therefore the , modems are used to transform a binary data stream into a signal suitable for transmission over the Public Switched Telephone Network (PSTN). The word modem is a concatenation of modulator and demodulator. A modulator accepts a binary data stream and modulates an analog signal (tone) in some combination of
