13/852643
Inventors:
Kofi Anim-Appiah - Morgan Hill CA, US
Hang Yan - Cupertino CA, US
Assignee:
Futurewei Technologies, Inc. - Plano TX
International Classification:
H04L 1/00
US Classification:
375296

US Patent:
20190199573, Jun 27, 2019
Filed:
Dec 26, 2018
Appl. No.:
16/232544
Inventors:
- Plano TX, US
Jianhua Liu - Shenzhen, CN
Bin Zhou - Shenzhen, CN
Kofi Anim-Appiah - Morgan Hill CA, US
Amir H. Fazlollahi - San Jose CA, US
International Classification:
H04L 27/36
H04L 1/00
H03M 13/25
H04B 3/52
H03M 13/23
H03M 13/11
Abstract:
A transmitter in a Digital Subscriber Line (DSL) system includes a rate encoder configured to generate a first set of encoded bits using a set of least significant bits, a trellis shaper configured to generate a second set of encoded bits using a most significant bit and the first set of encoded bits, a first constellation mapper configured to generate a first point described by integer coordinates in a complex plane based on the first set of encoded bits obtained from the rate encoder, a second constellation mapper configured to generate a second point described by integer coordinates in the complex plane after interleaving two bits from the second set of encoded bits obtained from the trellis shaper, and a merger module configured to merge the first point with the second point to generate a symbol. The symbol represents a third point described by integer coordinates in the complex plane.

US Patent:
20150280870, Oct 1, 2015
Filed:
May 27, 2015
Appl. No.:
14/722511
Inventors:
- Plano TX, US
Kofi Anim-Appiah - Morgan Hill CA, US
Hang Yan - Cupertino CA, US
International Classification:
H04L 1/24
H04B 17/11
H04B 17/336
H04L 1/00
Abstract:
A transmitter including a noise signal generator and a summing element is provided. The noise signal generator is configured to receive multiple noise settings and output multiple noise signals corresponding to the multiple noise settings. The summing element is configured to receive a transmit data signal and the multiple noise signals, sum one or more of the multiple noise signals with the transmit data signal, and output to a transmit driver configured to generate one of a single-ended and a differential signal based on the sum of the one or more of the multiple noise signals with the transmit data signal.
