摘要： There are provided a plurality of systems of reconfigurable radio processing unit (102) whose function and performance can be modified. A control unit (104) collects quality information on the communication link in communication methods received at respective radio processing systems (102a, 102b). According to this, the control unit (104) selects an optimal communication method and transmission mode from a plurality of communication methods and transmission modes (for example, diversity transmission between a plurality of systems, diversity transmission by a single communication method, and MIMO channel multiplex transmission). By modifying configurations of the reconfigurable radio processing unit (102) according to the selected communication method and transmission mode, it is possible to communicate at a desired transmission mode. Thus, it is possible to perform an optimal transmission to the communication link according to the quality condition and other request condition.

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.

摘要： A sampling mixer includes TAs (transconductance amplifiers), an in-phase mixer section connected to the TA and the TA, an opposite-phase mixer section connected in parallel with the in-phase mixer section, and a signal generator for generating a control signal for the in-phase mixer section and the opposite-phase mixer section respectively. The IIR filter using signals that underwent a current conversion by using the different transconductances is constructed, so that the filter characteristic can be designed by a weighting of the transconductance in addition to a capacitance ratio. As a result, the wide-band filter characteristic and the band-pass filter characteristic can be obtained, and deterioration of the receiving sensitivity can be suppressed by designing the filter characteristic suitable for the radio communication system.
