Abstract
A method and apparatus to reduce crosstalk in a communication system are described.
Claims18
A method, comprising:
- estimating a channel impulse response matrix;
- creating a crosstalk suppression filter matrix based on said channel impulse response matrix;
- and
- filtering a plurality of data streams received over a channel for a multiple input multiple output system to reduce far end cross talk between said data streams using said crosstalk suppression filter matrix.
1 more element
A multiple input multiple output system, comprising:
- a communications medium;
- a plurality of transmitters to connect to said communications medium, with each transmitter to transmit a data stream over said communications medium using a communications channel;
- a plurality of receivers to connect to said communications medium, said plurality of receivers to receive said data streams from said communications channel;
- and
- a crosstalk filtering module to connect to said plurality of receivers, said crosstalk filtering module to filter said data streams to reduce far end crosstalk noise incurred by said data streams during said transmission.
2 more elements
The multiple input multiple output system of claim 8, further comprising a plurality of equalizers to connect to said filtering module, said equalizers to equalize said filtered data streams using a set of substantially similar equalization parameters.
An apparatus, comprising:
- a plurality of receivers to receive a plurality of data streams transmitted over a communications channel;
- and
- a crosstalk filtering module to connect to said plurality of receivers, said crosstalk filtering module to filter said data streams to reduce far end crosstalk noise incurred by said data streams during said transmission.
An article comprising:
- a storage medium;
- said storage medium including stored instructions that, when executed by a processor, result in estimating a channel impulse response matrix, creating a crosstalk suppression filter matrix based on said channel impulse response matrix, and filtering a plurality of data streams received over a channel for a multiple input multiple output system to reduce far end cross talk between said data streams using said crosstalk suppression filter matrix.
