The invention relates to a novel
photon probability mapping method based on terrace forming, which belongs to the technical field of mapping method. The method comprises the following steps: matchingaccording to channel conditions and generating an optimal
Gaussian beam by a
laser; performing
probability matching by a probability matcher, and changing the shape of the
Gaussian beam by a spatial phase array to obtain a novel beam formed in terrace; performing the 64
QAM projection mapping on the data by the novel beam; concentrating and converging the 64
constellation point optical signals; performing pre-emphasis; amplifying the optical signals after passing through a channel, detecting by a
photodetector, performing low-pass filter, orthogonalizing and normalizing, and performing data convergence and
equalization; matching probabilistic solutions, removing step
noise by
wavelet transform analysis, performing
constellation demapping; estimating channel conditions according to the received data, feeding
back channel state information to the probability matcher, and performing real-time dynamic regulation on the probability matcher. The novel
photon probability mapping method based on the terrace forming can effectively reduce the
signal transmission power, reduces the
bit error rate, improves the
frequency band utilization, and lengthens the transmission distance.
