Abstract:
1. A system for interconnecting a plurality of computing devices comprising: a shared communication medium; a plurality of transceivers having a first and second port, the first port for connection to one of a plurality of computing devices and the second port for connection to said shared communication medium, each of said plurality of transceivers further comprising a transmitter and a receiver for transmitting and receiving time domain signals representing data, said time domain signals comprising a plurality of modulated carriers of predetermined frequency, over said shared communication medium to at least any one of other said plurality of transceivers; said receiver having a signal transformer for generating a frequency domain signal from the received time domain signal, and a frequency domain equalizer for operating on said frequency domain signal, said frequency domain equalizer comprising a single tap filter for each carrier of said plurality of modulated carriers received by said receiver; said transmitter transmitting at least one known symbol on at least two non-adjacent carriers and transmitting data symbols on carriers between said at least two non-adjacent carriers, and wherein said frequency domain equalizer generates filter taps for said each carrier in response to said at least one known symbol on said at least two non-adjacent carriers.
