N2 - Performance results are presented for digital subscriber line (DSL) precoders, also known as dynamic spectrum management (DSM) level 3, in terms of improvement of signal-to-noise ratio (SNR) and achievable bit rates under the very high speed digital subscriber line 2 (VDSL2) standard. Simulations were conducted using channel coefficients obtained from both empirical models and line measurements. The performance impact of various key factors is examined, including the number of lines, line lengths, frequency range, precoder design, channel measurement accuracy, and implementation accuracy (quantization errors). The results provide estimates of the achievable rate gains and offer guidance for the design and implementation of DSL precoders.
