Strong truncation photon compression system and method under ultra-large constellation scale
ActiveCN111049589AChange the degree of compressionSmall sizePhotonic quantum communicationElectromagnetic receiversCommunications systemEngineering
The invention discloses a strong truncation photon compression system and method under an ultra-large constellation scale so that ultra-large constellation scale is reduced to a small-scale constellation for light transmission. The compression degree of the whole constellation is changed by changing the compression parameters, so that the size of the constellation is greatly reduced. In the compression process, the constellation point probability is in Maxwell Boltzmann distribution, the center probability is the highest, and the probabilities of the two sides are gradually reduced, so that compared with an original signal under an ultra-large constellation scale, the signal has lower transmitting power, and the overall cost of optical communication is saved. Different compression parameters can change the size of a constellation to form constellation diagrams with different probability distributions, information entropies can be different along with the difference of the probability distributions, and the transmission bit rate can be changed along with the information entropies under the condition that the Baud rate is not changed. At a receiving end, if signals with different compression parameters are received, the access rates are different, so that the optical communication system also has certain flexibility.
