A method of communicating a bitstream having a characteristic Hamming weight to a destination via a channel comprises determining the characteristic Hamming weight of the bitstream, inverting each bit in the bitstream if the characteristic Hamming weight of the bitstream is below a threshold value and developing an indication of whether the bits in the bitstream are inverted, delivering the bitstream and the indication of whether the bits in the bitstream are inverted to the destination via the channel, and inverting each bit in the bitstream at the destination if the indication indicates that the bits are inverted.
