<p>A modulation scheme for HDTV, for example, uses a concatenated code comprised of a Reed-Solomon coder followed by an N-dimensional trellis coder whose N-dimensional output symbols with N > 1, are used to modulate a one-dimensional vestigial sideband modulator. Specifically, each N-dimensional s ymbol is a sequence of N one-dimensional signal points--specifically signal points of a one-dimensional VSB constellation.</p> |
