Abstract

A DSL system performs crosstalk cancellation using a plurality of vectoring cancellation chips that are partitioned into two or more groups based on DSL victim lines or DSL disturber lines or DSL tones. Embodiments of the invention include both single-criteria and double-criteria partitioning methods. In double-criteria embodiments, the vectoring cancellation VCE chips are first partitioned into two or more victim DSL line groups and then in each group the VCE chips are further partitioned by disturber DSL line processing. Alternately, the vectoring cancellation VCE chips are first partitioned into two or more disturber DSL line groups and then within each group further partitioned by victim DSL line processing. According to certain aspects, by partitioning the computation as described herein, the invention reduces the bandwidth and the number of links between the chips, without too much co-ordination complexity. This makes it feasible to partition across a larger number of chips, thereby allowing crosstalk cancellation across larger vectored groups.
