Line 29: Seems like their dot product is 4. <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures\|unsigned]] comment added by [[Special:Contributions/50.76.46.94\|50.76.46.94]] ([[User talk:50.76.46.94\|talk]]) 15:32, 23 March 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot--> If you take any two of these signals, their 'dot product' should (and I think does) come out to be zero. Actually, what's going on is that a transmitter transmits one code, and the receiver multiplies each of the samples it gets by ''its'' code, then sums the result. If the Tx and the Rx are using the ''same'' code, this will be positive or negative; if they're using a different code it will be zero.
