摘要： The overall throughput of the radio communication traffic in a radio communication area in a radio communication environment where a plurality of types of radio communication systems are mixedly used in a neighboring radio communication area is improved. When a multi-mode control station (101) performs communication with a terminal station in a network through a plurality of types of communication systems, a communication link parameter collecting section (10141) collects parameters indicating the states of the communication links. A resource allocation determining section (10143) determines communication resource allocation for which the throughput is the greatest for each resource allocation period according to the parameters. A communication control section (1015) controls a multi-mode communication unit (1012) according to the result of the determination.

摘要： A wireless communication method, a radio transmitter apparatus and a radio receiver apparatus wherein a signal sequence, which is used in a reception process using a first modulation scheme and can be generated from a signal sequence prepared for a reception process and used in a second modulation scheme, is employed, thereby achieving a performance to a similar extent to the reception process performance using the second modulation scheme. A radio transmitter apparatus (20) uses a first modulation scheme (e.g., OOK modulation scheme) to sequentially transmit, as a first sequence, both a sub-sequence a1(n), which is identical with a second sequence a(n) designed for use in a second modulation scheme (e.g., BPSK modulation scheme), and a sub-sequence a2(n), the bits of which are reverse to those of the second sequence a(n), in a time division manner. A radio receiver apparatus (30) detects the sub-sequence a1(n) and sub-sequence a2(n) in a received signal to send the detection result to the following stage for a signal processing.

摘要： A radio communication apparatus to be changed in function by software, when downloading software from a download server, first downloads software limited in operation and then configures a software radio section. After the configuration and the operation confirmation have been normally completed, execution-allowing key information is requested and received. Using it, reconfiguration is carried out in part thereby enabling all the operations. Accordingly, it is possible to safely carry out a download and a setting update of software to the radio communication apparatus.

摘要： A wireless communication apparatus and a communication control method wherein even if there occurs a change in communication control information due to a function change, an appropriate correction is implemented to improve the communication quality. A wireless communication apparatus (100) comprises a plurality of reconfigurable function parts (reconfigurable function modules (1031)) that reconfigure functions related to communication to perform digital signal processings according to a plurality of communication formats; and a communication operation control function part that controls the communication operation. Each of the reconfigurable function parts includes a property register (10311) in which the communication control information is written.

摘要： When data is transmitted on a burst basis, a symbol having a higher modulation level is inserted into parts of a burst on a symbol basis and this burst is transmitted. When the data including this burst is received on a burst basis, it is determined which symbol positions are inserted by the symbols having the higher modulation level and which symbol positions are inserted by the other symbols. This method allows increasing a communication capacity while retaining the reliability of the communication.

摘要： An FFT unit subjects a P-times oversampling output of an AD converter to Fourier transform into a frequency domain signal. A distortion estimation unit estimates a distortion characteristic from a difference between the frequency domain signal and a reference signal. A correction coefficient calculation unit calculates a correction coefficient of a distortion characteristic. A correction unit corrects the frequency domain signal by using the correction coefficient. An IFFT unit subjects the corrected frequency domain signal to inverse Fourier into a time domain signal having the same sampling speed as a symbol speed, and outputs a partial time series.

摘要： The present invention has an object to provide a wireless apparatus which is capable of correctly sampling a waveform of a pulse even when a shape of the pulse is varied.A synchronizing apparatus for causing an input signal to be synchronized with a clock signal is equipped with sampling unit 102, 103, and delay control unit 112. The sampling unit 102 and 103 sample the input signal at first sampling timing and second sampling timing, which are separated from each other in a predetermined time interval. The delay control unit 112 shifts both the first and second sampling timing during synchronous pull-in operation, and also, narrows the interval between said first and second sampling timing during synchronous follow-up operation. A synchronous status judging unit 105 judges whether or not the input signal is synchronized with the clock signal based upon a phase error amount outputted from a phase error calculating unit 104, and outputs the synchronous status to a delay amount control unit 106. The delay amount control unit 106 controls to increase/decrease delay amounts which have been presently set in variable delay devices 107 and 108 based upon the phase error amount outputted from the phase error calculating unit 104 and the synchronous status outputted from the synchronous status judging unit 105.
