Abstract
A method and apparatus for performing trellis coded modulation of signals for transmission on a TDMA channel of a cable network, such as a DOCSIS cable network, is provided. In an embodiment, an upstream modulator portion of a cable modem receives burst data, selectively encodes the burst data for trellis coded modulation to generate encoded symbols, and modulates the encoded symbols for selective transmission over a time division multiple access (TDMA) channel or a synchronous code division multiple access (S-CDMA) channel of the cable network.
