<P>PROBLEM TO BE SOLVED: To set a parameter for radio communication while preventing a circuit scale and consumption power from increasing when radio communication is performed in an electronic device or between electronic devices. <P>SOLUTION: A signal transmission device comprises: a signal generation unit 107 and a first set value processing unit 7100 at a front stage of a transmission path coupling unit 108 in a transmission side; and a signal generation unit 207 and a second set value processing unit 7200 at a subsequent stage of a transmission path coupling unit 208 in a reception side. The signal generation unit 107 and the signal generation unit 207 perform prescribed signal processing based on set values. The first set value processing unit 7100 inputs a predetermined set value for the signal generation unit 107 to the signal generation unit 107, and the second set value processing unit 7200 inputs a predetermined set value for the signal generation unit 207 to the signal generation unit 207. Because the set values are not dynamically changed depending on situations such as a change in environment, reduction in a parameter calculation circuit and power consumption is achieved, and if the device is used in a state where there is no environmental change, the parameter calculation circuit is not wasted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
