Wireless transmission of data is effected across a communications channel defined by a communications medium by means of an encoder, operable to apply a low density parity check (LDPC) code to data for transmission. The LDPC code is irregular with respect to the degree of variable nodes, and so the transmitter further comprises means for sorting encoded data with respect to the corresponding variable node degree, and modulation and distribution means for allocating encoded and sorted data onto the communications medium. The distribution of the data onto the communications medium is carried out with respect to a prior established pre-coding algorithm, such as SVD.
