    摘要： A method for transmitting signals for interference randomization is disclosed. The method for transmitting signals includes spreading the transmission signals using a plurality of orthogonal codes and transmitting the transmission signals spread by the plurality of orthogonal codes by a spatial frequency block coding (SFBC) or spatial time block coding (STBC) scheme. Among the plurality of orthogonal codes, codes of which mutual interferences are equal to or greater than a predetermined threshold are grouped to the same group, and orthogonal codes belonging to different groups are used for the spreading of the signals which are transmitted at the same timing. Accordingly, it is possible to realize interference randomization.

    摘要： A channel coding method of variable length information using block code is disclosed. A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A−10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.

    摘要： An FEC apparatus and method is provided that uses turbo codes. An input frame is iteratively decoded until an iterative decoding stop command is received under a predetermined control, and the absolute reliability of each symbol in the frame is output. The minimum of the absolute reliabilities is detected as a measurement, and a threshold is detected using the a-priori information and extrinsic information of the each symbol. The measurement is compared with the threshold, and the iterative decoding stop command is output according to the comparison result.

    摘要： A forward error correction method for decoding coded bits generated by low density parity check matrixes. The method comprises converting each of the coded bits into a log likelihood ratio (LLR) value, and applying the converted values to variable nodes; delivering messages applied to the variable nodes to check nodes; checking a message having a minimum value among the messages, and determining a sign of the message having the minimum value; receiving messages updated in the check nodes, adding up signs of the received messages and a sign of an initial message, applying a weighting factor of 1 when all signs are identical, and when all signs are not identical, updating a message of a variable node by applying a weighting factor; determining LLR of an initial input value; and hard-deciding values of the variable nodes, performing parity check on the hard decision values, and stopping the decoding when no error occurs.
