PROBLEM TO BE SOLVED: To provide a wireless receiver that can realize transmission quality required by each application with a proper and minimum consumed power regardless of a state of a transmission channel. SOLUTION: An analog signal wirelessly sent after modulation is sampled by a prescribed frequency, and converted into a digital signal with a corresponding prescribed bit width, the digital signal after analog/digital conversion is demodulated to obtain received data, an error rate of the received data after demodulation is calculated, and at least any of the sampling frequency of the analog/digital converter, or the operating frequency of a demodulator and the bit width of the digital signal is changed depending on a comparison result between the calculated error rate and a target error rate of an application corresponding to the received data so as to solve tasks above. |
