Higher-order QAM packs more bits per symbol but requires better signal-to-noise ratio (SNR).

Modulation is the process of varying a carrier signal to represent data. Common techniques include: Amplitude Shift Keying (ASK) Frequency Shift Keying (FSK) Phase Shift Keying (PSK) wireless communications from the ground up pdf

. Unlike traditional academic textbooks that rely on dense, high-level calculus, this work uses an intuitive, visual approach to explain how signals travel through the air and are processed by code. Higher-order QAM packs more bits per symbol but
