  • Patent number: 8498326
    Abstract: A multi-tone transceiver with a components forming a transmit path and a receive path configured to couple via a subscriber line to an opposing multi-tone transceiver for frequency division multiplexed multi-tone modulated communications therewith is disclosed. A noise margin channel identifier is configured to identify within a received tone set, discrete tones each associated with a corresponding one of at least two channels differing from one another in a relative noise margin of associated tones. A Viterbi decoder is responsive to the channel identification provided by the noise margin channel identifier to discretely decode each of the at least two channels; thereby improving the fidelity of the error correction provided by the Viterbi decoder by discretely processing the identified channels within the received set of tones.

  • Patent number: 6693890
    Abstract: An acquisition module for acquiring signal timing in a CDMA system has a register for storing and organizing synchronization code, at least 4 match filters for match filtering between I/Q samples and the corresponding synchronization code, at least 4 absolute value blocks for determining absolute values of match filtering results, a summation function for summing results obtained through match filtering and through absolute value taking, and a control logic for controlling the acquisition process, characterized in that the acquisition module loads a 64-bit section of synchronization code and I/Q complex samples and match filters them in a simultaneous manner and, upon registering a value greater than a preset threshold, acquires an initial timing, the initial timing being verified over the remaining 64-bit sections of synchronization code using the same control circuitry used in acquiring the timing.
