Simulation for a crosstalk avoiding algorithm in multi-conductor communication

Multi-conductor communication is widely used in electronic applications for fast data transfer between different devices. The most common multi-conductor transmission media are Cat 6 Ethernet cables, flat cables and backplanes. Between N+1 conductors one has N independent potential differences, hence when N+1 conductors are available, one may in principle transfer N signals, but the crosstalk between the signals in such case would be huge. Therefore, in all applications, the communication is implemented by differential transmission of signals (between (N+1)/2 pairs), so through N+1 conductors, one transfers (N+1)/2 signals, i.e. for big N, one transmits about half the number of possible signals (and even in this case, there is crosstalk between the transmitted signals). Hence, the crosstalk limits the information rate. The current work presents a general algorithm for transferring the maximum number of possible signals, without crosstalk, while keeping the multiconductor transmission line matched. This algorithm has been validated by simulating it with the ANSYS commercial software and we present in this work the results of this simulation.
