Methods and devices for adaptive data coding/decoding

Development of adaptive codecs based on sequential and/or parallel coding schemes, specialized methods of iterative, multi-threshold and neural network decoding, which make the possibility for increasing of the communication channel bandwidth using efficiency.

Developed:

• method of encoding/decoding information based on variable codes with low density of parity checks;

• multidimensional linear iterative codes, characterized by increased correcting ability due to the implementation up to 9 different linearly independent parity checks;

• W-packet interleaving / data deinterleaving technique.

• Neural network decoding methods of linear block codes based on RNN and RBF;

• method of decoding the fountain LT-code to correct errors of the “erasure” type;

• method of parallel concatenated probabilistic decoding of low density parity checks codes;

• method of adaptive multi-threshold decoding of multidimensional iterative codes;

• a method for measuring the quality parameters of binary channels in the process of multidimensional iterative codes adaptive decoding in real time and without disconnecting communication.

• software tools for modeling the encoding / decoding processes in communication channels (ASDecoder, CascadeCode MPD, etc.)
