Webconstructs a Huffman codebook while it processes the sensor signals, without the need for performing encoding in two passes. As a consequence, neither signal buffering is required nor the transmission of a whole codebook from the encoder to the decoder, as the latter can construct the codebook inferred from the received symbols. Web21 okt. 2024 · Encoding the codebook The advantage of a canonical Huffman tree is that it can be encoded in fewer bits than an arbitrary tree.
