1. A method comprising:
obtaining an in-phase (I) input signal and a quadrature (Q) input signal at a quadrature modulator; and
performing constant envelope bi-phase shift keying (CE-BPSK) modulation using the quadrature modulator to generate a modulated output signal;
wherein the modulated output signal comprises a CE-BPSK modulated waveform containing phase reversals, the CE-BPSK modulated waveform having a substantially-constant amplitude during the phase reversals; and
wherein the quadrature modulator causes the modulated output signal to step through a number of phases during each phase reversal while maintaining the substantially-constant amplitude.
