Description

<p>This paper describes the results measured with a radio evaluation system using under-sampling when the frequency difference between carrier and local signals changes continuously. In addition, we show the correction performance by estimating the frequency difference before and after correction. As a result, the phase fluctuation within the correction range could be corrected. Meanwhile, it was clarified that the element of the fluctuating frequency difference affects the signal evaluation and that there is a residual frequency difference after correction.</p>
