摘要： In order to transmit variable length encoded data in low signal to noise ratio environments, a first data pattern is added to a beginning portion of encoded data to signify a beginning of the encoded data. Further, a second data pattern is added to end portion of the encoded data to signify and end of the encoded data. Additionally, since the encoded data may naturally include the second data pattern and thereby mistakenly indicate an end of the encoded data, the encoded data is first checked for such a pattern. If the pattern is found within the encoded data, a new pattern is substituted therefore. In order to counter errors, patterns similar to the first data pattern are also substituted with new patterns. As such, a variable length encoded data can be transmitted in a low signal to noise ratio environment, and can thereafter be easily decoded.
摘要翻译：为了在低信噪比环境中发送可变长度编码数据，将第一数据模式添加到编码数据的开始部分，以表示编码数据的开始。此外，将第二数据模式添加到编码数据的结束部分以表示和结束编码数据。此外，由于编码数据可能自然地包括第二数据模式，从而错误地指示编码数据的结束，所以首先检查编码数据的这种模式。如果在编码数据中找到模式，则会替换新的模式。为了对抗错误，类似于第一个数据模式的模式也被新的模式所取代。因此，可变长度编码数据可以在低信噪比环境中传输，并且此后可以容易地解码。

摘要： A system and method that efficiently compresses data sets that contain one or more repetitive data values. Substitute symbols represent repeated data sequences in the compressed data output. Data sequences that terminate with one or more of a particular value are specially processed by storing their substitute symbols separately from the general substitute symbol dictionary so that they are able to be more efficiently accessed. Substitute symbols for contiguous data sequences that consist of those particular values are also stored separately. The preferred embodiment specially processes data sequences that contain data bytes equal to zero.

摘要： A data decompressor for decompressing an input stream of compressed codes to recover an output stream of data characters corresponding thereto. A plurality of character tables corresponding to respective characters store strings of data characters, the stored strings having respective string codes associated therewith. A string comprises a prefix string of at least one character followed by an extension character. A string is stored in the character tables by storing the code associated with the string prefix in the character table corresponding to the string extension character at a character table location corresponding to the string code of the string. The character tables are accessed with a currently received compressed code so as to recover a string corresponding thereto and the characters of the recovered string are output. An extended string is inserting into the character tables comprising the string corresponding to the compressed code received previously to the currently received compressed code extended by the first character of the recovered string, the extended string being stored in the character tables by storing the previously received compressed code in the character table corresponding to the first character of the recovered string at the character table location corresponding to the string code assigned to the extended string. A directory linking the string codes to respective character tables in which the strings corresponding to the string codes are stored is utilized in accessing a stored string.

摘要： We present a method and apparatus for performing adaptive data compression. An alphabet and vocabulary in the encoder and decoder is built adaptively and stored in a dictionary as symbols are to be encoded and decoded. Each time an unknown symbol is to be encoded by the encoder, the encoder adds the symbol to the dictionary and transmits it in plain in the encoded string. The code words transmitted by the encoder include symbols and indexes. The state of a prefix bit preceding the code word indicates whether the code word is a plain symbol or an index of a symbol or string of symbols stored in the dictionary. The decoder examines the prefix bit of each code word as it is received to determine if the code word stores a symbol in plain or in index. If the code word stores a symbol in plain, the decoder learns the symbol by adding a sequence of symbols resulting from the concatenation of previously decoded symbols and the first symbol of the currently decoded symbol and by adding the symbol to its dictionary. If the code word stores an index, the decoder decodes the code word by extracting the symbol or sequence of symbols stored in the dictionary at the respective index in the dictionary.

摘要翻译：我们提出一种执行自适应数据压缩的方法和装置。编码器和解码器中的字母和词汇表被自适应地构建并存储在字典中，因为符号将被编码和解码。每当编码器对未知符号进行编码时，编码器将符号添加到字典中，并以编码字符串的形式将其传输。由编码器发送的码字包括符号和索引。代码字之前的前缀位的状态指示代码字是否是存储在字典中的符号或符号串的简单符号或索引。解码器检查每个代码字的前缀位，因为它被接收以确定代码字是否以简单或索引存储符号。如果代码字平原存储符号，则解码器通过将从先前解码的符号的连接和当前解码的符号的第一符号产生的符号序列并通过将符号添加到其字典来学习符号。如果码字存储索引，则解码器通过在字典中的相应索引处提取存储在字典中的符号或符号序列来解码码字。

摘要： A method of macro-compressing a software product made up of one or more separate software packages matches strings having a predetermined minimum length with each other. The matching strings are expanded in size by including adjacent software. A compressed software object is formed by producing software blocks from the largest expanded matching strings and including assembly information that tells how to reconstruct the remaining strings from the software blocks. The software packages may either be data objects or executable objects. A method of producing a maximally compressed software product first macro-compresses the software product, and subsequently micro-compresses it. Micro-compression matches strings of the macro-compressed software product, each having a predetermined maximum size and separated from each other by a maximum distance, and eliminates redundant strings.

摘要： An apparatus and method for providing an encoded signal with an encoder. The encoder includes an encoding stage and a selection stage. The encoder receives a first external encoded signal, a first external unencoded signal and an external selection signal. The encoding stage encodes the first external unencoded signal to generate a first internal encoded signal. The selection stage internally routes within the encoder one of the first external encoded signal and the first internal encoded signal to an output of the encoder in response to the external selection signal.
