Current DSL systems cancel FEXT in both downstream and upstream directions using a technique called vectoring. FEXT is cancelled even when two or more bonded pairs serve the same subscriber. In this paper, we propose a method to exploit FEXT between these lines rather than mitigating it. FEXT across the lines serving different subscribers will still be cancelled. This system may be considered a multi-user...
Vectoring based on Tomlinson-Harashima Precoding (THP) has been proposed for downstream FEXT cancellation in G.fast DSL system. However, it suffers from the lack of scalability and latency accumulation due to nonlinear THP, especially for a large number of ports. In this paper, we propose a novel precoding technique based on a single DSL Access Multiplexer (DSLAM) that hosts multiple Vector Processors...
Next generation wireless cellular 5G networks operating in mmWave band target a peak rate of 10Gb/s for both outdoor and indoor applications. However, in this frequency band penetration through brick pillars, concrete walls, and tinted glass hits a barrier of 30dB or more attenuation. An outdoor RF/relay station has to be placed along with an indoor RF/relay station and a mechanism to connect the...
