- What is the concept fractional sampling?
- Is there a relationship between the fractional sampling and interpolation?
- And how does the fractional sampling help in convert the SIMO (Signal input multi-output) channel into SISO (single input signal output)?
For the first question, you can get enough details in the paper https://ieeexplore.ieee.org/document/4394307/ , for second question, there is not direct relation but you can read about fractional sampling then you will know the relationship between them. the third question, refer to the paper in link https://ieeexplore.ieee.org/document/1344460/ .. Just read the two papers and if something still not clear, let me know.
