<p>A system for serial communication comprising an encoder (220) for serially outputting conservative encoded codewords responsive to a parallel data input, and a decoder (220) for outputting, in parallel, decoded data words responsive to the serially transmitted conservative encoded codewords. The codewords are characterized in that the ratio is known between the total number of bits per codeword transmitted and the total number of transitions per codeword. The encoder (220) transforms each m-bit parallel data word into one n-bit codeword, where n is greater than m, such that every codeword has a known number of transitions and such that one of the transitions in the codeword has a predefined position. Thereafter, the encoder (220) converts each n-bit codeword from parallel to serial form for output onto a serial communications channel (210).</p> |
