Huffman coding," Mathematical and Computer Modelling, vol.
The inner loop quantizes the input vector and increases the quantization step size until the output vector can be coded by
Huffman coding with the available amount of bit.
Finally, the encoder produces compressed signal with the help of
Huffman coding in .AAC format.

Huffman coding scheme can also be applied to code word length [L.sup.[xi]] (A) for code word length [N.sub.i]; the average length [L.sup.[xi]] (A) of Huffman code satisfies
The quantized coefficients are rearranged in a zigzag or adaptive block scan [19] order to be further compressed by an efficient lossless coding strategy such as run length coding, arithmetic coding, or
huffman coding. The decoding is simply the inverse process of encoding.
