Description:
Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called prefix-free codes , that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol). Huffman coding is such a widespread method for creating prefix codes that the term Huffman code is widely used as a synonym for prefix code even when such a code is not produced by Huffman s algorithm.-

Description: Huffman coding and Compression algorithm c++ code
In computer science and information theory, a Huffman code is an optimal prefix code found using the algorithm developed by David A. Huffman while he was a Ph.D. student at MIT, and published in the 1952 paper A Method for the Construction of Minimum-Redundancy Codes .[1] The process of finding and/or using such a code is called Huffman coding and is a common technique in entropy encoding, including in lossless data compression. The algorithm s output can be viewed as a variable-length code table for encoding a source symbol (such as a character in a file). Huffman s algorithm derives this table based on the estimated probability or frequency of occurrence (weight) for each possible value of the source symbol. -Huffman coding and Compression algorithm c++ code

程序执行方法 : decoder.exe codebook compressed_file de_DavinciCode.txt-Huffman decoding (3) Huffman Decode, decode the compressed file, reducing DaVinciCode.txt (Da Vinci Code) throughout the text. u Title reasons: Huffman Coding for multimedia signal processing technology is very important, whether in text, images, audio compression, there are using this technique, the physical meaning behind the communication master Claude Shannon s information theory. u purpose: to make students familiar with Huffman Coding theory and implementation, although Huffman coding by hand painting the whole process is very simple, but in order to write the program algorithms, data structures must use multiple techniques, such as dynamic arrays and free allocation , linked list to use, or even to write recursive procedure method.

Description: 要求对一段数据序列进行哈夫曼编码，使得平均码长最短，输出各元素编码和编码后的数据序列。
①组成序列的元素是[0-9]这10个数字，每个数字其对应的4位二进制数表示。比如5对应0101，9对应1001。
②输入数据序列的长度为256。
③先输出每个元素的编码，然后输出数据序列对应的哈夫曼编码序列。(Design a 1MHz FIR low pass filter.
Huffman coding is required for a section of data sequence to make the average code length the shortest, and the output of each element encoding and the encoded data sequence.
The elements of the sequence are the 10 Numbers [0-9], each of which corresponds to a 4-bit binary representation.
Let's say 5 is equal to 0101, and 9 is equal to 1001.
The length of the input data sequence is 256.
First output the encoding of each element, and then output the data sequence corresponding Huffman coding sequence.
Requirements:
(1) clock signal frequency 16MHz;
(2) input signal bit width of 8bits, symbol rate of 16MHz
Requirements in Matlab FIR filter floating-point and fixed-point simulation, and determine the FIR filter tap coefficient
(4) write the test simulation program.) Platform: |
