Abstract
The present invention is directed to unique methods and apparatus for suppressing impulse noise in a multipoint communications environment using a linear block interleaver. One representative embodiment comprises first logic configured to arithmetically combine a time series of input symbols into a block of N-symbol combinations, and second logic configured to transmit, on a separate channel, each N-symbol combination to a receiver. The first logic is located in a transmitter of a first communications device. The time series has size N and N is greater than one, and each of the input symbols is taken from a signaling constellation.
Claims19
A communication system comprising:
- first logic configured to combine a time series of N input symbols into a block of output symbols, wherein N is greater than one, wherein the block comprises N output symbols, wherein each of the output symbols comprises a combination of the N input symbols, wherein each of the input symbols is taken from a signaling constellation, and wherein each output symbol is associated with a respective one of a plurality of different channels, such that a stream of ideal reference symbols when re-interleaved generates error signals;
- and
- second logic configured to transmit each output symbol on one of the plurality of different channels.
A method comprising:
- combining a time series of N input symbols into a block of output symbols, wherein N is greater than one, wherein the block comprises N output symbols, wherein each of the output symbols comprises a combination of the N input symbols, wherein each of the input symbols is taken from a signaling constellation, and wherein each output symbol is associated with a respective one of a plurality of different channels, such that a stream of ideal reference symbols when re-interleaved generates error signals;
- and
- transmitting each output symbol on one of the plurality of different channels.
A communication system comprising:
- means for combining a time series of N input symbols into a block of output symbols, wherein N is greater than one, wherein the block comprises N output symbols, wherein each of the output symbols comprises a combination of the N input symbols, where each of the input symbols is taken from a signaling constellation, and wherein each output symbol is associated with a respective one of a plurality of different channels, such that a stream of ideal reference symbols when re-interleaved generates error signals;
- and
- means for transmitting each output symbol on one of the plurality of different channels.
A program embodied in a computer-readable storage medium, the program comprising:
- first logic configured to combine a time series of N input symbols into a block of output symbols, wherein N is greater than one, wherein the block comprises N output symbols, wherein each of the output symbols comprises a combination of the N input symbols, wherein each of the input symbols is taken from a signaling constellation, and wherein each output symbol is associated with a respective one of a plurality of different channels, such that a stream of ideal reference symbols when re-interleaved generates error signals;
- and
- second logic configured to transmit each output symbol on one of the plurality of different channels.
