All-digital transmitters are getting increased attention due to its closer proximity to the ideal software-defined radio (SDR) transmitter. In this paper we propose a new transmitter architecture that addresses two key limitations of current approaches, namely, the poor coding efficiency and the high quality factor requirements of the RF output reconstruction filter that significantly limit the practical usability and dissemination of these new flexible RF transmitters.
