Abstract
A waveform generator for generating a waveform in a dual mode wireless device includes a first waveform generator portion (,) and a second waveform generator portion (,). The first waveform generator portion includes a first register (,) connected in series with a second register (,) and a first feedback selector (,), and the second waveform generator portion includes a third register (,) connected in series with a fourth register (,) and a second feedback selector (,). The first register and the third register, and the second register and the fourth register are set up as accumulators, and a new output data value of the first and third register is obtained by adding a corresponding previous data value of the first register and the third register, respectively, and a corresponding previous data value of the second register and the fourth register, respectively, and a new data output value of the second and fourth register is obtained by adding a corresponding previous data value of the second register and the fourth register, respectively, and a scaled previous output data value of the first and third registers.
