Abstract:
A system and method for transmitting a baseband real signal with a non-constant envelope using a polar transmitter involves decomposing a baseband real signal into a non-constant envelope signal of the baseband real signal and a sign signal of the baseband real signal, where the sign signal restores zero crossing regions of the non-constant envelope signal, modulating a carrier signal with the sign signal of the baseband real signal to generate a modulated signal, converting the non-constant envelope signal of the baseband real signal into a voltage signal using a voltage controlled supply regulator, amplifying the modulated signal into an amplified signal based on the voltage signal, and transmitting the amplified signal to an external wireless device.
