Digital modulation maps bits to waveform symbols. BPSK uses two phases (0°, 180°) to represent bits 0 and 1; its symbol error rate over AWGN with energy per bit Eb and noise spectral density N0 is Pe = Q(√(2Eb/N0)). Higher-order QAM trades power/complexity for spectral efficiency but requires higher SNR to maintain the same error rate.

: While older systems used AM/FM, modern wireless is almost entirely digital. Modulation Schemes : ASK, FSK, and PSK : Shifting Amplitude, Frequency, or Phase. Wireless Communication From The Ground Up Pdf
