ASK (Amplitude Shift Keying): Digital modulation technique where amplitude of carrier is varied

FSK (Frequency Shift Keying): Digital modulation where frequency of carrier is varied

PSK (Phase Shift Keying): Digital modulation where phase of carrier is varied

QAM (Quadrature Amplitude Modulation): Combines amplitude and phase modulation

OOK (On-Off Keying): Simplest form of ASK where carrier is switched on/off

MSK (Minimum Shift Keying): Special form of continuous-phase FSK

Symbol Rate (Baud Rate): Number of symbol changes per second

Bit Rate: Number of bits transmitted per second (bps)

Constellation Diagram: 2D representation of modulated symbols

Nyquist Rate: Minimum sampling rate to avoid aliasing (2× bandwidth)

Eye Diagram: Oscilloscope display of digital signal quality

Modulation Index: Measure of extent of modulation applied

BER (Bit Error Rate): Ratio of erroneous bits to total transmitted bits

SNR (Signal-to-Noise Ratio): Ratio of signal power to noise power

Eb/N0: Energy per bit to noise power spectral density ratio

SER (Symbol Error Rate): Probability of incorrect symbol detection

Bandwidth Efficiency: Bit rate per unit bandwidth (bps/Hz)

Power Efficiency: Required Eb/N0 for target BER

OFDM (Orthogonal Frequency Division Multiplexing): Multi-carrier modulation

Spread Spectrum: Techniques that spread signal over wider bandwidth

Adaptive Modulation: Dynamically changing modulation scheme

MIMO (Multiple Input Multiple Output): Using multiple antennas
