Title:
LOW-ORDER HDSL2 TRANSMIT FILTER
Document Type and Number:
WIPO Patent Application WO2002060056
Kind Code:
A3
Abstract:
The present invention comprises a method of obtaining coefficients for a transmit filter such that the power spectral density of the output for the different frequencies comes close to but does not exceed a maximum power spectral density of a communication(s) standard. By first doing a convex optimization procedure to obtain the autocorrelation coefficients for the filter and then using the autocorrelation coefficients to determine the filter coefficients, a low-order filter that closely approximates the desired output power spectral densities can be produced.
