BASE STATION RECEIVING EQUIPMENT OF RADIO COMMUNICATION SYSTEM WITH CODE CHANNEL SEPARATION Russian patent published in 1998 - IPC

FIELD: radio communications. SUBSTANCE: receiving equipment has n receivers one of whose outputs functions as data output, second output is connected to inputs of received signals level analyzer 7, third one is connected to inputs of control unit 6. Inputs of receiver receivers 1 are connected to outputs of switch 5 whose right-hand group of inputs is connected to outputs of first matching device 2 and left-hand one, to those of second matching device 4. Input of second matching device 4 is connected through rejection unit 3 of high-power phase- modulated broadband signals to output of first matching device 2 whose input functions as equipment input. Outputs of level analyzer 7 are connected to inputs of control unit 6 whose outputs are connected to inputs of switch 5. EFFECT: reduced necessity of equipment transmitter power control while increasing carrying capacity of system or reduced requirement to number of power gradings and accuracy of their setting. 6 dwg
