Abstract
A new transmit architecture for digital radios is proposed that emphasizes the use of pre-computed waveforms stored in memory instead of real-time computation. We present results that show how direct synthesis techniques can be extended to directly generate many types of digitally modulated waveforms such as PSK or QAM. These techniques are especially appropriate for software radios implemented on systems with general purpose processors and large memory systems
