BROADBAND SIGNAL RECEIVING DEVICE Russian patent published in 2006 - IPC H04B7/00 

FIELD: broadband radio communications; noise-immune signal transfer in very-long, long, and medium wavebands.

SUBSTANCE: proposed device has series-connected first receiving unit 1, analog-to-digital converter (ADC) 4, signal storage and compression unit (SCU) 9, digital-to-analog converter 12, correlator unit 15, voltage-to-number converter unit 20, correlating convolution storage unit (CSU) 21, maximal number selection unit 19, and comparison unit 18 whose second input is connected to read-only memory (ROM) 17 whose output is connected to control unit 11; inputs and outputs of the latter are connected to SCU 9, data allocation unit 19, and maximal number selection unit 19; outputs of control unit 11 are connected to CSU 21, ROM 17, correlator unit 15, unit 20, and reference-signal shaper 10; output of the latter is connected to unit 15 whose input is connected to data allocation unit 2; output of SCU 9 is connected to ADC 4. Enhanced noise immunity is attained due to post-detection storage of correlating convolutions. Search time is reduced due to use of sequential detection procedure. In addition, data allocation and signal tracking are effected using search correlators which makes it possible to dispense with all real-time processing units.

EFFECT: enhanced noise immunity if device.
