| Feb 18, 2021 at 7:43 | comment | added | Florian | Thanks that maps my intuition. The first condition is the one that's potentially troublesome as $v[n]$ contains $q[n]$ which is the result of applying the quantizer so it may not be entirely independent of $x[n]$. Would this still work of $x[n]$ were a composition of a strong and a weak signal (such that, say, the noise power is between the two)? I am really trying to find all conditions on $x$ and $w$ that must be satisfied for this to work. | |
