    • PROBLEM TO BE SOLVED: To reduce the power consumption of a receiver and easily and properly calculate the weight without deteriorating the quality of a radio signal received by the receiver when using the receiver configured such that an adaptive array antenna and an adaptive equalizer are connected in series. SOLUTION: A radio base station 100 includes a decision unit 150 which determines whether the improvement effect of a second signal quality with respect to a first signal quality is a desired value or below by comparing the first signal quality of a first output signal y 1 [k] output from an adaptive array antenna 110 and the second signal quality of a second output signal y 2 [k] output from the adaptive equalizer 120. When the improvement effect is determined to be the desired value or below by means of the decision unit 150, a control unit 160 stops power supply to the adaptive equalizer 120 and calculation of an equalization weight c * in a weight calculation unit 140, and makes the receiver 101 output the first output signal y 1 [k] as an output signal Out.

    • PROBLEM TO BE SOLVED: To provide radio communication equipment capable of improving precision in detecting frames. SOLUTION: In a radio communication equipment 1, a first frequency band is used as a first communication channel, and a second frequency band containing the first communication channel and a second communication channel is used as a third communication channel. It includes a signal intensity measuring part 40 which outputs a detection signal if the power of a reception signal exceeds a threshold value, a matched filter 41 which functions as first and second filters when it detects the frame of the first and third communication channels, and a control part 42 which discriminates the presence of a frame in the second communication channel based on the presence of the detection signal as well as the detection result of the matched filter 41, and makes the matched filter 41 function as the first filter when the frame is present in the second communication channel while makes it function as the second filter when the frame is not present.
