摘要 |
A multi-tone modem with components forming a transmit path and a receive path configured to couple to a wired communication medium for at least intermittent communication of frequency division multiplexed multi-tone modulated communication channels thereon. A Fourier transform component transforms received communication channels between a time domain and a frequency domain and vice-versa. Selected components on the receive path determine alignments between the received multiplexed communication channels in the time domain using alignment determinations made in both a time domain and frequency domain portions of the receive path. The Fourier transform component transforms a stream of digitized samples of the received multiplexed communication channels from the time to the frequency domain using the alignment determinations made by the selected components on the receive path. |

1. A multi-tone modem with a plurality of shared and discrete components forming a transmit path and a receive path configured to couple to a wired communication medium for at least one of time division multiplexed (TDMA) communication and carrier sense multiplexed (CSMA) communication of a plurality of multi-tone modulated communication channels thereon, and the multi-tone modem comprising:
a scheduler component shared between the transmit and receive paths, and configured to schedule transmission of individual ones of the communication channels with other multi-tone modems network coupled to the wired communication medium during successive simplex intervals and to aggregate within a successive single multiplexed interval, transmission receipt acknowledgments (ACKS) therefore, thereby improving a data transfer capability on the wired communication medium, wherein the simplex intervals each comprise a single time interval of the TDMA or CSMA communication during which only one of the plurality of communication channels of the communication medium is being used. |
