METHOD FOR ADAPTIVE INFORMATION TRANSFER Russian patent published in 2005 - IPC

FIELD: information transfer technologies.

SUBSTANCE: in the method, via channel with non-zero conductive ability a set of M stochastic (n,k,q) codes is used with correction of errors with guaranteed in any channel upper limit of decoding error possibility due to use for all codes of same code base q, each of codes is optimal for certain quality of channel, prior to information transfer conductive ability of channel is checked by transferring testing set, in form of q-base stochastic (n,1,q) code, conductive ability of channel is determined by pair-wise comparison of q-based symbols of received block of (n,1,q) code and counting number of matching symbols N, parameters n and k of optimal (n,k,q) code are selected with correction of errors, information exchange is performed by code blocks of selected code with correction of errors and detection of blocks with error repetition factor exceeding correcting ability of code, blocks are transferred again with uncorrected errors, share of blocks with uncorrected errors is calculated within range of analysis with length G of last received blocks, compliance of this share to range of optimality criterion of effective code is checked on basis of current state of channel, on exit beyond limits of code optimality code parameters n and k and checking matrix H are altered synchronously for sending and receiving sides of channel.

EFFECT: higher speed of operation, higher resistance to interference, higher trustworthiness, higher efficiency.
