ADAPTIVE PSEUDORANDOM-SEQUENCE SEARCH DEVICE Russian patent published in 2006 - IPC H04L7/04 

FIELD: radio engineering; communication systems using broadband signals.

SUBSTANCE: proposed device has series-connected multiplier 1 whose input functions as device input, adder 5, solving device (SD) 4, pseudorandom sequence generator status register 7, buffer register 12, coincidence circuit 13, counter 14, switching unit 9, and pseudorandom sequence generator 2; second output of the latter is connected through status register 7 to second input of coincidence circuit 13. Second output of status register 7 is connected through switch 8 to second input of pseudorandom sequence generator 2, second input of switch 8 being connected to output of counter 14. Two outputs of clock generator 3 are connected to two inputs of switching unit 9 and to two inputs of control circuit 10 one of whose outputs is connected to second input of SD 4 and two other outputs, to inputs of memory device 6 and through buffer register 11, to input of adder 5. Output of the latter is connected to input of memory device 6 and through buffer register 11, to input of adder 5. Output of adder 5 is connected to input of memory device 6 whose output is connected to input of buffer register 11.

EFFECT: reduced search time.
