There isn't a prohibition on using codes in ham radio. The 
prohibition is on trying to conceal the meaning of a 
transmission. Hams use many codes, the "Q" codes are very 
common. Their meaning is listed in may places, so they are like 
the Uniform Commercial Code before/during WW2.

Spread spectrum is permitted, if the spreading codes are 
published. Different digital encodings are permitted, if 
encoding is published. etc.

Cheers - Bill
