Line 31: 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.--[[User:IanHarvey\|IanHarvey]] ([[User talk:IanHarvey\|talk]]) 11:40, 22 October 2012 (UTC) == Dubious == The text claims that a Soviet mobile phone was 3 cubic metres in size. This can't possibly be correct. That's equivalent to about 106 cubic feet<sup>[https://www.google.com/search?q=3+cubic+metres+in+cubic+feet]</sup>, or the entire interior capacity of a 2007 Ford Crown Victoria<sup>[http://www.motortrend.com/cars/2007/ford/crown_victoria/specifications/interior.html]</sup>.
