Class Summary

Class	Description
ConvolutionalCoder	Encode an input sequence with a convolutional code.
DeScrambler	Descramble the input bit sequence using a feedback shift register.
HadamardCode	Produce a Hadamard codeword by selecting a row from a Hadamard matrix.
HammingCoder	Encode the information symbols into Hamming code.
HammingDecoder	Decode a (n, k) Hamming code, where n is specified by parameter codedRate and k is specified by parameter uncodedRate.
HuffmanBasic	Given a probability distribution, generate the Huffman code book.
HuffmanBasic.Node	A class that defines the node in binary tree that is used to construct the codebook of Huffman code.
HuffmanCoder	Given a probability distribution and alphabet, encode the input using Huffman code and send the result in booleans to the output port.
HuffmanDecoder	Given a probability distribution and the corresponding alphabet, decode the input using Huffman code and send the result to the output port.
LempelZivCoder	Lempel-Ziv encoder.
LempelZivDecoder	Lempel-Ziv decoder.
Scrambler	Scramble the input bit sequence using a feedback shift register.
Slicer	The Slicer functions as a decoder of the LineCoder.
TrellisDecoder	The TrellisDecoder is a generalization of the ViterbiDecoder.
ViterbiDecoder	The Viterbi algorithm is an optimal way to decode convolutional and trellis codes.
