The Requirements of the error components for the SSR in WPAN
초록
영어
The modulation quality of the I/Q modulator in a wireless transmitter usually affects system performance and it mostly depends on both a nonlinearity and a distortion, from the third order intermodulation(IM3) signal and the error components such as an input amplitude error and a local phase error, respectively. This paper focused on how much the Single Sideband Ratio(SSR), which indicates the signal distortion, changes according to the variation of the error components. Consequently, since a desired signal, side band signal at the I/Q modulator output are also represented with those power series coefficients and the error components, the effects
of the error components on SSR to meet the EVM specification of the WPAN can be clearly analyzed Keywords: SSR(Single Sideband Ratio), Imperfection features, I/Q modulator
