Modern telecommunications require more and more data transmission capacity, which can be limited by the available frequency band and signal power.
The invention presented in this document consists of a method and a system for building high-performance digital signal constellations. The constellations built according to the present invention make it possible to transmit a greater amount of information with more efficient energy consumption.
The MTCE method aggregates symbols (vectors) that are coplanar in the geometric space of signals. This allows the construction of efficient constellations with a large number of symbols. The high-order statistical moments between symbols in MTCE constellations are reduced, which reduces the non-linear effects generated by the transition between symbols.
The MTCE method is based on a topological mapping between four-dimensional geometric space and three-dimensional geometric space. The topological mapping relates the electrical signals in four dimensions to the polarization states of the optical carrier, which are commonly represented in three dimensions.
