A transmitting device configured to obtain a message to be transmitted; map the obtained message onto a two-dimensional 2-symbol constellation to obtain a sequence of discrete constellation symbols, where n is an odd number not less than 3. A receiving device configured to receive a sequence of noisy discrete constellation symbols; demap the sequence of noisy discrete constellation symbols to output data using a two-dimensional 2-symbol constellation, where n is an odd number not less than 3.

Class of symbol constellations for data transmission

The invention presents an equalizing device, a corresponding method and an optical signal with a frame structure for enabling the method. The equalizing device includes a first 2&#xd7;2 MIMO equalizer configured to perform a first equalization on the digital signal, supported by a 2&#xd7;2 MIMO channel estimation of the channel based on the digital signal. Further, the device includes a second 2&#xd7;2 MIMO equalizer, arranged after the first equalizer and configured to perform a second equalization on the digital signal, supported by a State of Polarization (SOP) estimation of the optical signal based on the digital signal.
