摘要： Presently known d=l codes have long trains consisting of consecutive 2T runs and an overall high frequency of occurrence of the shortest 2T runs that reduce the performance of the bit detector. By using a code with an MTR constraint of 2 an improvement in the bit detection is achieved. A code constructed in a systematic way that provides an MTR constraint of 2 is presented. A variation of such a code is disclosed where one sub-code is used, where coding states are divided into coding classes and where code words are divided into code word types. Then, for a given sub-code, an code word of type t can be concatenated with an code word of the next sub-code if said subsequent code word of said next sub-code belongs to one of coding states of the coding class with index T

摘要： A method of, and apparatus for, encoding a serial stream of digital data blocks (characters) comprises partitioning the stream into the data blocks; translating the blocks into corresponding encoded equivalents; and assembling the encoded equivalents together to generate an output serial stream of encoded data. The method is characterised in that; each encoded equivalent includes equal numbers of logic O's and logic 1's; the encoded equivalents are mutually distinguishable such that a single bit error in one or more of the equivalents is unambiguously detectable; each value of data block uniquely maps onto a corresponding encoded equivalent and at least one equivalent is a marker equivalent for which is periodically inserted in the output stream to denoting where equivalents occur in the output encoded data. The method of encoding data provides the benefit of addressing issues of synchronisation, reducing bit error rate, and balance simultaneously.

摘要： At a transmission node, at least part of control information is divided into M (M: a natural number) control information blocks of an N-bit length (N: a natural number of 1 to 7), and each control information block i (i = 1 to M) is given a control information parity of a predetermined (8 to N) bit length so that it is encoded by the predetermined control information bit array into M control information codes of a length of 8 bits and is subjected to a control information transmission processing. Here, the control information parity and the control information bit array are such that the humming distance of each of the control information codes is at least d (d: a natural number of 2 to 8) and such that the humming distance of each of the codes of a control information 10B is at least D (D: a natural number of 2 to 10). At a reception node, the control information code is divided into a control information block and a control information parity, a parity test is made, and a detected error, if any, is error-processed.

摘要： In an orthogonal frequency division multiplexing (OFDM) system (10) which uses an outer Reed-Solomon encoder and interleaver (24) and an inner convolutional encoder (26), after the inner convolutional encoding the data bits are interleaved by an inner interleaver (28), and then grouped into symbols, each symbol having "m" bits. After grouping, the symbols are mapped to a complex plane using quadrature amplitude modulation (QAM). Thus, bits, not symbols, are interleaved by the inner interleaver (28). A receiver (12) performs a soft decision regarding the value of each bit in each complex QAM symbol received.

摘要： A method to encode two digital signals (USC-B, UBC-B) is disclosed. Each of the digital signals is characterized by a bit stream. An N bit block from the first signal is mapped to a unique M bit third signal where M is greater than N. Further, the number of 1's in the M bit third signal is less than M/2. The M bit third signal is transmitted in the event a bit from the second signal is 0, whereas the complement of the M bit third signal is transmitted in the event a bit from the second signal is 1.
