DATA TRANSFER SYSTEM USING VARIABLE-PARAMETER NOISE-IMMUNE CODE Russian patent published in 2005 - IPC

FIELD: digital data transfer systems including those using variable-parameter noise-immune code, such as adaptive noise-immune concatenated code.

SUBSTANCE: newly introduced in system on sending end are transmitting-part code parameter register, transmitting part control signal distributor, and transmitting-part switching unit; control input of system transmitting part is connected to input of transmitting-part code parameter register whose first output is connected to control input of external code encoder and second output, to first data input of transmitting-part switching unit; transmitting-part synchronization input of system is connected to input of transmitting-part control signal distributor whose first output functions as control input of sync pulse train generator; newly introduced on receiving end are receiving-part switching unit, internal-code syndrome computing circuit, internal-code syndrome decoder, and code parameter computing unit; synchronization input of system receiving part is connected to input of control signal distributor whose control input is connected to output of frame synchronization device and output, to syndrome decoder input.

EFFECT: enhanced digital data transfer speed, data reception noise immunity, and reliability in transmission of noise-immune code parameters.
