A method of encoding a binary source message u, by calculating x:=Au, calculating y:=B′x, resolving the equation Dp=y for p, and incorporating u and p to produce an encoded binary message v, where A is a matrix formed only of permutation sub matrices, B′ is a matrix formed only of circulant permutation sub matrices, and D is a matrix of the form D = ( T 0 … 0 0 0 T … 0 0 … … … … … 0 0 … T 0 I I … I I ) where T is a two-diagonal, circulant sub matrix, and I is an identity sub matrix.
