<P>PROBLEM TO BE SOLVED: To provide a method for quantizing an input signal of N samples into a string of (k) symbols drawn from a q-ary alphabet. <P>SOLUTION: A complementary method reproduces a minimally distorted version of the input signal from the quantized string, given some distortion measure. First, an [N, k]<SB>q</SB>linear error-correcting code that has a sparse generator factor graph representation is selected. A fixed mapping from q-ary symbols to samples is selected. A soft-input decoder and an encoder for the SGFG codes are selected. A cost function is determined from the input signal and a distortion measure, using the fixed mapping. The decoder determines an information block corresponding to a code word of the SGFG code with a low cost for the input signal. The input signal can be reproduced using the encoder for the SGFG code, in combination with the fixed mapping. <P>COPYRIGHT: (C)2005,JPO&NCIPI | ||||||

PROBLEM TO BE SOLVED: To map a code on one transmission symbol. SOLUTION: A convolution coder 201 for external codes applies convolution arithmetic operation to received data at a coding rate of 2/3 and outputs the result of the arithmetic operation to an interleaver 202. The interleaver 202 interleaves date received from the convolution coder 201 and outputs the result to a convolution coder 203. The convolution coder 203 for inner codes applies convolution arithmetic operation to the data from the interleaver 202, at a coding rate of 1(=3/3) and outputs the result of arithmetic operation to a multi- valued modulation mapping circuit 204. The multi-valued modulation mapping circuit 204 maps the data received from the convolution coder 203 to the transmission symbol of an 8PSK modulation system. | ||||||

PROBLEM TO BE SOLVED: To obtain a process which can protect a bit to be transmitted from an error introduced from a transmission channel. SOLUTION: An encoder form a second sequence of bits Cn containing a redundant subset based on a sequence of information bits to be transmitted and generates a third sequence of bits dn by performing differential encoding in the form of an exclusive OR operation between the bits Cn and f(n) (f(n)<n). Transmitting signals obtain likelihood data rn related to the bits dn and a receiver calculates the estimated value of the bits of the redundant subset as the function of rn and rf(n) , detects the bit Cn of a subset having an erroneous estimated value by utilizing the redundancy, and corrects the less-reliable codes of two related likelihood data items rn and rf(n) . | ||||||

Apparatus, systems and methods for error detection in transmissions on a multi-wire interface are disclosed. A method for correcting transmission errors in multi-wire transition-encoded interface may include determining whether a symbol error is present in the sequence of symbols based on a value of an error detection code (EDC) in the received plurality of bits, generating one or more permutations of the sequence of symbols, where each permutation includes one symbol that is different from corresponding symbols in the sequence of symbols and different from corresponding symbols in other permutations. A permutation in the one or more permutations may be identified as including a corrected sequence of symbols when it produces a decoded EDC value that matches an expected EDC value. The expected EDC value may correspond to a predefined value for EDCs transmitted over the multi-wire interface to enable detection of up to two symbol errors at the receiver. | ||||||

A method and system of detecting colluders conducting a collusion attack including a minority-type collusion attack on a digital product includes the generation of codewords used as watermarks in the digital product. The inner code of the codewords is generated using permutations of rows in a Hadamard matrix and concatenating them together. A typical outer code of the codeword is the Reed Solomon code. An adaptive detector is able to accurately detect one of three or more colluders of a minority-type attack. Prior art schemes using an error correcting code-based watermarking mechanism with an inner code fail to detect colluders with a minority-type collusion attack which includes three colluders. |
