Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/115609
Kind Code:
A1
Abstract:
The present art relates to a signal processing device, a signal processing method, and a program with which it is possible to specify the frequency band for a user band allocated to a reception device. A command output unit (125) uses an ODU_UBxSignal_ON command to cause a switch (41) to output signals for all frequency bands. A spectrum measurement unit (123) measures the signal level of an RF unit (101) that is measured by an automatic signal power control unit (108), and stores the result in a spectrum storage unit (124). Thereafter, the command output unit (125) supplies, to the switch (41), an ODU_PowerOFF command for requesting discontinuation of signal output of a predetermined user band. A power measurement unit (127) measures a power measurement value, and a power change measurement unit (128) measures the difference between the power measurement value and a power measurement value prior to the output of the ODU_PowerOFF command. A band specification unit (129) specifies the frequency band associated with a larger power difference as the frequency band of the predetermined user band, and stores the result in a UB storage unit (126). The present art can be applied to a reception device.
