metanoiaWorking with Huawei. Metanoia, also known as Yi Chung, stays under the radar but they continue active in technical fora. They have participated in the UNH-BBF plugfests and have appeared occasionally at trade shows. As you can see from the spec sheets below, their chips are aimed at the mainstream G.fast market, They worked with Soft At Home on an SFP reference design. 

They also have been filing patents. These are by Chun-che Chang 

12/17/15 - 20150365131 - Crosstalk management for ofdm communication systems in power efficient transmission mode
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...

11/13/14 - 20140334283 - Dynamic rate adaptation methods in a vectored g.fast system
The present disclosure provides mechanisms, systems, methods, techniques and devices for dynamic rate adaptation in a vectored G.fast system. More specifically, a flexible framework that incorporates with residual crosstalk noise is provided.... 
Inventors: Chun-che Chang, Sam MungallTien-ke Huang(Metanoia Communications Inc.)

09/18/14 - 20140269957 - Dynamic bandwidth allocation in ofdm communication systems
Various embodiments of a mechanism of dynamic allocation of bandplan are provided. In one aspect, a communication device utilizes a bandplan during initialization in a digital communication system. The communication device modifies the bandplan after one or more channel estimations to optimize data rates of communications in a downstream direction...
