Interference Alignment for DSL

Inter-line interference, known as crosstalk, is the most significant source of performance degradation for Digital Subscriber Line (DSL) systems. Vectored DSL is an effective technique for he elimination of crosstalk; however, there are many scenarios in which Vectored DSL is not implementable or practical. Interference alignment is presented as a technique to solve these issues. In particular, the combination of partial vectoring and interference alignment is proposed. The practical advantages of partial vectoring and interference alignment over Vectored DSL are discussed. Finally, simulation results are provided o demonstrate the potential performance gains of the proposed approach.
