An interleaver and scheme for interleaving in which highly correlated bits are maximally separated. The scheme involves interleaving a set of bits to be delivered to a modulation system that utilizes a quantity of N carrier frequencies. A first block of N consecutive bits is assigned to each of N bins, on a one-bit-per-one-bin basis. The aforementioned assignment proceeds in a particular sequence. A second block of N consecutive bits is assigned to each of the N bins, on a one-bit-per-one-bin basis. The second block is assigned in the same sequence the first block was assigned. The second block is consecutive to the first block.
