None Phase Truncation Error DDS Implementation
Zheng Wang · Microelectronics & Computer · 2011
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 signal 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.
