Summary:Methods and apparatus are described for implementing low-density parity-check codes. These may be used in electronic communications, such as wireless communication systems. A number of processes are implemented for each vector in a plurality of vectors of a coding matrix associated with a low-density parity-check code. These include retrieving, from one or more interleavers, one or more addresses, using the or each retrieved address to retrieve one or more symbols from data and determining a parity-check operation corresponding to a particular said vector using said one or more symbols retrieved from said data. This enables an encoded block to be generated using said data and each of the parity-check operations. It also enables a received code vector to be decoded.
