对于无线数字通信而言，通常将数字用户信号首先转换到模拟域中，然后通过一个或两个步骤将其调制到无线电频率。
For wireless digital communications, digital user signal is usually at first converted into analog domain and then modulated to radio frequency by one or two steps.
无线电”“年代频率刻度盘上的数字保持不变。
The digits on the radio's frequency dial stay the same at all times.
所以CORDIC算法来实现软件无线电直接数字频率合成器有助于节省芯片面积、降低功耗、减少成本。
Thus, software radio DDFS based on CORDIC algorithm can help to reduce chip area, power dissipation and cost.
