Title:
MULTIPLEXER
Document Type and Number:
Japanese Patent JP2017200111
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress SNR deterioration of an uplink signal of each RE which is output from a multiplexer to an REC.SOLUTION: The multiplexer includes a receiver unit, a calculation unit, a determination unit, a cutoff unit and a multiplexing unit. The receiver unit is provided on a radio device basis, to receive an uplink signal transmitted from the radio device. The calculation unit calculates an uplink signal power value received by the receiver unit. Using the uplink signal power value calculated by the calculation unit, the determination unit determines whether or not the uplink signal includes only noise of the radio device which transmits the uplink signal. When the uplink signal is determined to include only the noise by the determination unit, the cutoff unit cuts off the noise signal which is the uplink signal including only the noise. The multiplexing unit multiplexes an uplink signal which is received by the receiver unit and is not cut off as the noise signal by the cutoff unit, to output the same to a radio control device.SELECTED DRAWING: Figure 1
