Abstract:
Aspects of a method and system for polar modulation with discontinuous phase are provided. In this regard, in-phase and quadrature-phase components may be generated from a modulated baseband signal, and the signal components may be utilized to generate a signal representative of the amplitude of the baseband signal. Furthermore, the signal components may be pulse shaped and the pulse-shaped components may be divided by the signal representative of the amplitude of the baseband signal. The resulting signals may be up-converted to RF, summed, and amplified, where the amplification may be controlled via a quantized representation of the signal representative of the amplitude of the baseband signal. In this regard, one or more bias points, and/or one or more binary weighted current sources coupled to one or more power amplifiers may be controlled. The pulse-shaping may comprise passing the signal components through a raised cosine filter.
