How to remove alien noise?
- Alien Noise is the crosstalk typically from non-VDSL users, using the same bundle.
How to allocate power across different tones, also called Optimal Spectrum Balancing
Key parameters:
- To get the best performance ( Data Rate)
- Minimize the computational complexity
- Involves efficient receiver and transmitter design
