Title
* RF Direct Orthogonal Phase Under-Sampling Technique for Software Defined Radio
Highlight
We will demonstrate a novel sampling technique, "RF direct orthogonal phase under-sampling technique", that maintains the appropriate amount of vector information even in conditions of under-sampling. The technique implements an ideal Software Defined Radio. Maintaining an accurate sampling frequency is a very important part of the technique because the number of phase errors directly increase with deviations of sampling frequency. Therefore, we will demonstrate our newly developed RF-carrier recovery technique.
