Patent number: 9634780Abstract: The present disclosure outlines mechanisms, systems, methods, techniques and algorithms that gateway devices and powerline communication (PLC) networks can follow to mitigate adverse effects from the aforementioned inter-network interference. Although the present disclosure provides implementation details for G.hn and VDSL2, the mechanisms, systems, methods, techniques and algorithms described herein are equally applicable to other similar technologies. Therefore, when referring to non-implementation specific systems, methods, techniques and algorithms the term PLC is used to refer to a powerline network and the term customer premises equipment (CPE) is used to refer to a home-gateway device.Type: GrantFiled: April 15, 2014Date of Patent: April 25, 2017Assignee: METANOIA COMMUNICATIONS INC.Inventors: Sam Mungall, Ravi Mantri

Publication number: 20150365131Abstract: In the present disclosure, several techniques are proposed to estimate the worst-case crosstalk noise and use it for bit-loading and SRA calculations so that fluctuating crosstalk when PET mode is enabled does not lead to system instability. One of the proposed techniques involves strategically placing some marker tones in the transmitters of the affecting lines. The noise floor may be inferred by interpolating the noise observed on these marker tones (tones that are always-on) and applying to the entire frequency band on the victim line. Another proposed technique involves periodically transmitting a set of marker symbols (fully loaded OFDM symbols), so that a victim channel can estimate the SNRs in a worst case crosstalk scenario.Type: ApplicationFiled: August 21, 2015Publication date: December 17, 2015Inventors: Chun-Che Chang, Ravi Mantri

Patent number: 8861650Abstract: Described herein are a technique, method, device and system related to reducing memory requirements and complexity in receivers. According to the present disclosure, the capability to request precoded ACE symbols is added to receivers in a mode under the g.hn MIMO standards that uses precoding to enhance the capacity of links. Using precoded ACE symbols, memory requirements for the receiver can be reduced as it is not necessary for the receiver to save the precoder coefficients. Additionally, the frequency of updates required for the precoding coefficients can be reduced by adapting the MIMO decoder using the precoded ACE symbols as reference symbols.Type: GrantFiled: December 2, 2012Date of Patent: October 14, 2014Assignee: Metanoia Communications Inc.Inventor: Ravi Mantri
