Abstract
Methods and systems are described for reduction of crosstalk in multi-wire communications systems using ensemble codes. Constraints applied to code construction and/or permissible encoding sequences eliminate transmit patterns shown to generate capacitively coupled and/or inductively coupled crosstalk.
Claims20
A method comprising:
- receiving a set of input data bits and responsively generating a plurality of sets of modulus-converted data bits;
- selecting, for each set of modulus-converted data bits, a corresponding cross-talk reduction codeword vector from a set of crosstalk reduction codeword vectors, wherein each of the crosstalk reduction codeword vectors eliminates patterns of adjacent vector elements associated with either an inductive or capacitive constructive interference;
- and
- transmitting each selected crosstalk reduction codeword vector on a multi-wire bus.

A system comprising:
- a plurality of signal conductors configured to receive a set of input data bits;
- a bit generator connected to the signal conductors configured to receive the input data bits and to responsively generate a plurality of sets of modulus converted data bits;
- a logic encoding circuit connected to the bit generator configured to form, for each set of modulus converted data bits, a corresponding crosstalk reduction codeword vector, wherein each crosstalk reduction codeword vector eliminates patterns of adjacent vector elements associated with either an inductive or capacitive constructive interference;
- and
- a transmit driver configured to emit the crosstalk reduction codewords onto a multi-wire transmission bus.
