Abstract: Disclosed herein is a method of transmitting data, the method comprising: obtaining a plurality of data blocks; determining a plurality of values of a transmission parameter for a transmitter; determining a plurality of values of a processing parameter of a processor; determining, for each of the obtained data blocks, one of a plurality of compression levels in dependence on at least one of the determined transmission parameter values and/or at least one processing parameter values; compressing each of a plurality data blocks in dependence on the determined compression level each block; and transmitting the data blocks; wherein: the transmitted data blocks comprise data blocks are compressed with different compression levels; and one of the compression levels is a determination to not compress data blocks such that the method does not compress some of the transmitted data blocks.

Abstract: Disclosed herein is a method for determining how to encode data in accordance with a systematic coding technique and encoding data in accordance with the determined systematic coding technique, the method comprising: determining the code parameters n, k, r and B, wherein n is the total number of nodes, k is the total number of nodes of source data, r is the total number of nodes of redundant data, such that n=k+r, B is the number of substripes of data in each of the nodes such that all of the nodes of source data and all of the nodes of redundant data comprise the same number of substripes, wherein k is 2 or more and B is 3 or more; determining nodes of source data that comprise source data that is not encoded by the systematic coding technique, wherein all of the B substripes in the nodes of source data store binary values only; and for each of the substripes of each of the nodes of redundant data, determining to generate the substripe of redundant data in dependence on a generator matrix; and encoding subst

Abstract: Disclosed herein is a method of generating a generator matrix for defining how to systematically code source data, the method comprising: determining source nodes for comprising a plurality of sub-stripes of source data, wherein the number of source nodes is K and the number of sub-stripes of source data comprised by each source node is S; determining redundant nodes for comprising a plurality of sub-stripes of coded data, wherein the number of redundant nodes is R and the number of sub-stripes of coded data comprised by each redundant node is S; determining values of a first generator matrix according to a systematic coding technique such that K of the rows of the generator matrix to define how to generate all of the K source nodes as comprising source data and R of the rows of the first generator matrix define how to generate all of the R redundant nodes as comprising combinations of two or more of the source nodes; generating a second generator matrix, with a first dimension (K×S) and a second dimension ((
