Abstract :
This paper provides a new approach to mitigate the crosstalk interference in the symmetric digital subscriber line (SDSL) upstream transmission. A vector channel equalizer has been proposed for the SDSL upstream receiver to enhance spectral compatibility for the SDSL services. This approach outperforms a conventional scalar equalizer, which used in the current SDSL systems, has about a 15 dB gain in mean squared error (MSE). It significantly suppresses the crosstalk degradation and ensures the quality of service (QoS) on the SDSL transmission throughput. Moreover, the enhancement of the SDSL receiver can benefit the extension of the SDSL deployment coverage range and also guarantees promising data rates on increasing numbers of customer subscribers
