A goal in the software radio design philosophy is to place the analog-to-digital converter as near the antenna as
possible. This objective has been demonstrated for the case of a single input signal. Bandpass sampling has been applied to
downconvert, or intentionally alias, the information bandwidth of a radio frequency (RF) signal to a desired intermediate frequency.
The design of the software radio becomes more interesting when two or more distinct signals are received. The traditional approach
for multiple signals would be to bandpass sample a continuous span of spectrum containing all the desired signals.
The disadvantage with this approach is that the sampling rate and associated discrete processing rate are based on the span of spectrum as opposed to the information bandwidths of the signals of interest.

一个是理论的原理,一个是实现的方案。你就算对原理很懂了,在座项目的时候还是会发现很多问题光靠原理是解决不了的。当然了,不懂原理,那更是一筹莫展。

才注意到,这是带同采样,不靠谱吧?

其实一直都觉得带通采样不靠谱,最稳定的还是基带采样。
