I will keep caps to acronyms though! :-) Jason, For the basestations, I said hundreds of MHz not tens. I used 20Hz in the example. I have personally worked on such stations and they work just fine. :-) | |

It's also a little misleading to suggest that cellular base stations directly sample at radio frequency and use undersampling. While there may be some element of undersampling used, good receivers typically downconvert from RF to an intermediate frequency (IF) that is suitable for sampling. Among many other reasons, sampling in upper Nyquist zones is much more sensitive to sample-time jitter, so you would not want to do this for a tens-of-MHz-wide signal centered at 1-2 GHz, for example. | |
