摘要： If it is judged by a signal from a first signal processing unit that a signal of a first communication system is not received and it is judged by a signal from a second signal processing unit that a signal of a second communication system is received, wireless communication is performed by the second communication system. If it is judged that the signals of the first and the second communication systems are received, a system judging unit judges which communication system is to be used for the wireless communication, based on the signals from the first signal processing unit and the second signal processing unit. If the wireless communication is to be performed by the first communication system, diversity reception or transmission is performed by first and second antenna elements.

摘要： Provided are a direct sampling circuit and a receiver using a discrete time analog process and having a filter effect of a steep attenuation characteristic in a narrow-pass band without lowering a sampling rate. In a discrete time direct sampling circuit (13), the positive phase side and the inverse phase side are both sampled by a local signal for a differential current output of a differential voltage/current conversion unit (1011) and electric charge is accumulated in a charge sampling capacitor. The latest accumulated charge at the positive phase side and charge accumulated at the inverse phase side before a predetermined number of samples are combined with the charge accumulated in a history capacitor (1043) in the past. Thus, it is possible to realize equivalently high-degree FIR filter characteristic.

摘要： There are provided a sampling filter that enables a filter characteristic to be adjusted flexibly, and a radio communication apparatus equipped with this sampling filter. A sampling filter apparatus (100) is equipped with four integration units (150-1 through 150-4) corresponding to the number of filter taps, and some of the integration units (150-1 through 150-4) include an integrator having an MEMS structure. By this means, a charge amount (accumulated charge amount) of a received signal integrated by an integrator can be adjusted by adjusting the capacity of an integrator having an MEMS structure. A received signal amount emitted from an integration unit can also be adjusted by adjustment of the integration amount of a received signal, enabling the filter characteristic of the sampling filter apparatus (100) to be adjusted flexibly.

A first signal mixing section mixes the first band-restricted signal and the first phase-shifted signal. A second signal mixing section mixes the second band-restricted signal and the second phase-shifted signal. A phase difference calculation section calculates the phase difference value from the first mixed signal and the second mixed signal stripped of frequencies other than a desired baseband frequency. A polarization calculation section calculates reception polarization from the first reception field intensity value, second reception field intensity value and phase difference value.

摘要： A method of calculating coefficients determining excitation amplitudes and phases for obtaining a desired antenna pattern of a circular array antenna comprising a plurality of antenna elements disposed circularly. Coefficients for a linear array antenna having the same number of antenna elements as the circular array antenna are determined by a Fourier series expansion in integral limits calculated from a beam direction and a beam width that are estimated from incoming radio waves and then are transformed into the coefficients for the circular array antenna. With this method, the beam direction and the beam width of the antenna pattern of the circular array antenna can be set at will. Consequently, this method enables adaptive control of sectored beams of sectored antennas at a base station or the like used for a mobile communication system, thus enhancing efficiency of the use of the antennas.
