Abstract
A method includes obtaining an in-phase (I) input signal and a quadrature (Q) input signal at a quadrature modulator. The method also includes performing constant envelope bi-phase shift keying (CE-BPSK) modulation using the quadrature modulator to generate a modulated output signal. The modulated output signal includes a CE-BPSK modulated waveform containing phase reversals, and the CE-BPSK modulated waveform has a substantially-constant amplitude during the phase reversals.
