Problem with manchester code for RF

[dhouston]

dhouston, How can you say: Manchester encoding is not immune from noise but does have built-in error detection. What is the "built-in error detection"? This is news to me as I write software for Tire Pressure Monitoring equipment which uses Manchester coding. Please explain.....

If you don't see a change of state at the middle of a bit period, you've detected an error which is usually the result of noise if you are using it over a wireless link or a collision if you're using it over a wired link (e.g. 802.3, X-10). See the last paragraph at http://www.wildpackets.com/support/c...ignal_encoding.
