摘要： An apparatus and method for decoding low density parity check (LDPC) codes are provided. A memory module configured by a plurality of unit memories stores a reliability value. Variable node processors perform a computation associated with a variable node, and update data of the memory module in a column direction, respectively. Check node processors perform a computation associated with a check node, and update data of the memory module in a row direction, respectively. A parity checker determines if all errors have been corrected such that an iterative decoding process is performed. A memory access control module selects a unit memory to be updated by a variable node processor or a check node processor.

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.
