Not disguised, merely efficient. If you are trying to maximize the 
information rate of you signal in the presence of noise for a particular 
transmission power, your signal ends up looking like noise. After 
spending more than 30 years purely in the digital domain, I'm now 
working for a company that make IP-over-satellite equipment. I was 
astounded to discover that a really efficient signal looks like noise.
