In this paper we propose a semi-blind time domain equalizer (TEQ) design method for VDSL system. In the VDSL system frequency division duplex is used to separate upstream and downstream signals. In downstream or upstream transmission , only half the tones carry data and the other half are null tones. The proposed semi-blind method exploits the null tones of(More)
—In this paper, we propose an eigen-based semiblind time-domain equalizer (TEQ) design method for VDSL systems. We exploit the fact that the VDSL system is frequency-division du-plexing and maximize signal-to-interference ratio in the frequency domain. Unlike earlier eigen-based TEQ designs, the proposed method does not require the channel impulse response(More)
In this paper we propose a semi-blind time domain equalizer (TEQ) design method that maximize SIR (signal-to-interference ratio) in frequency domain for VDSL systems. The proposed method exploits the training symbols in VDSL initialization using an eigen approach. Unlike earlier eigen based TEQ designs, the proposed method does not require the channel(More)
