Abstract

By modifying the traditional Direct Digital Synthesizer (DDS) design method

a novel solution without phase truncation error is introduced in this paper. It has reduced the storage requirement for the sine-wave samples

eliminated the storage limitation to the signal precision improvement

and avoided the infection which comes from the phase truncation error to the final signa1 spectrum; consequently

the DDS performance is meliorated. This method is applicable in carrier generation

frequency-offset modulation and some other communication signal processing area

and could be implemented on many hardware platforms such as FPGA

DSP and MCU.
