Digital Modulation Schemes

• Memoryless Modulation Methods– Pulse Amplitude Modulation (PAM)

– Phase Modulation or Phase-Shift Keying (PSK)

– Quadrature Amplitude Modulation (QAM)

– Multi-dimensional Signaling

• Signaling Schemes with Memory– Continuous-Phase Frequency-Shift Keying (CPFSK)

– Minimum-Shift Keying (MSK)

– Offset QPSK (OQPSK)
