Title: Digital receiver
Inventor: OYA MASAHIKO
IPC: E05B49/00
Filed: 2010-08-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption while properly removing noise signal in a digital receiver.SOLUTION: Based on the transmission timing of a request signal, "a period during which a wanted wave signal Sk is not received" (a specified time T3) is recognized. During "the period in which a wanted wave signal Sk is not received," the signal that is received is a noise signal Sn. Consequently, such configuration and control as are related to discrimination whether the reception signal is the noise signal Sn or wanted wave signal Sk can be omitted, and based on the noise signal Sn, a filter coefficient of an adaptive filter 31 can be set. Consequently by omitting the control related to discrimination of the signal, the power consumption related to the process can be reduced.
