Title: Radio wave receiver
Inventor: OBATA KATSUSHI
IPC: H04W28/04
Filed: 2013-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a radio wave receiver capable of achieving both improved reception success rate and suppressed power consumption.SOLUTION: A radio wave receiver 4 normally has a standard value of a reception frequency which is the number of times of reception preparation operation per unit time. This enables the reception frequency to be normally suppressed to a small number of times, to suppress power consumption of the radio wave receiver 4. The radio wave receiver 4 calculates a bit error rate Kx of reception data when receiving a radio wave. If the bit error rate Kx is within a predetermined range, it can be said that reception is in an almost established situation although not satisfied. Therefore, if the bit error rate Kx of the reception data is a criterion value or lower, the radio wave receiver 4 has an increased reception frequency to enhance the possibility of radio wave reception.
