Classes
class	CC_Encoding
	Convolutional encoding class. Supports any k,n with k<n. The input bits of a symbol are clocked simultaneously into the right hand side, or least significant position of the internal registers. Therefore the given polynomial representation of generators should follow the same convention. More...
