摘要:
A wireless transmitter comprises ID signal storage module for storing an ID signal that identifies a group to which a data signal to be transmitted belongs and provides, for each group, second or higher-order statistic properties unique to each group; modulator for modulating the data signal; wireless signal ID assignment module for associating the modulated signal thus modulated with the stored ID signal and for generating a signal to be transmitted, by assigning second or higher-order statistic properties that correspond with the ID signal to the modulated signal that is associated with the ID signal; and wireless signal transmission module for wirelessly transmitting the signal thus generated.

A radio communication apparatus includes a characteristic data extraction unit receiving a radio signal from one or more radio stations and calculating characteristic data representing a waveform characteristic indicating statistical properties of the received signal; a characteristic data determination unit determining at least one characteristic data based on one or more calculated characteristic data; a signal generation unit converting a signal for a radio transmission into a signal having a format corresponding to the determined characteristic data, and generating a transmission signal having a characteristic waveform based on the characteristic data; and a transmission unit transmitting the transmission signal.

The receiver, which enables rejection of image signals with higher accuracy over wider frequency band, can be provided as a low IF receiver by inputting a calibration signal of frequency fi (1≦i≦N) before reception of signals and determining the frequency response fa(z) to fd(z) of a calibrating filter in a filter mismatch calibrating circuit (FIL_CAL) 195 to make zero amplitude and phase mismatches between the I component and Q component of the quadrature demodulation signal at the frequency fIFi.

A clearing section includes a counter for measuring a period up to the reset of contents set by means of an operation panel to initial values. If a position discriminating section discriminates that the operation panel is at a first position, the clearing section starts measuring the period by means of the counter from the first entry made to the operation panel. When a count value reaches a predetermined value, the clearing section executes an automatic clear processing to reset the contents set by means of the operation panel to the initial values. On the other hand, the clearing section cancels the execution of the automatic clear processing if the position discriminating section discriminates that the operation panel is at a second position.
摘要:
A signal frequency band detection device is disclosed that is able to separately handle plural co-existing signals, and able to separately detect frequency bands used for transmission of these co-existing signals. The signal frequency band detection device includes a signal decomposition unit that decomposes a received signal into plural signal components with frequency bands of the signal components at least partially overlapping each other; and a frequency band detection unit that, based on respective electrical powers of the signal components, detects the respective frequency bands of the signal components.

A signal detector arranged in a receiver of a wireless communication device includes a variable passband bandpass filter configured to bandlimit a received signal using a variable passband; a signal parameter detection unit configured to detect a signal parameter of each of a plurality of signals contained in the received signal; a detection order determination unit configured to determine a detection order for detecting the signals from the received signal based on the signal parameter; a parameter control unit configured to control the passband of the variable passband bandpass filter based on the detection order and the signal parameter; and an equalization and decision unit configured to equalize and decide the bandlimited signal output from the variable passband bandpass filter. The signals contained in the received signal are successively detected from the received signal according to the detection order by means of the variable passband bandpass filter and the equalization and decision unit.

In a portable telephone apparatus, the length of a housing thereof and a display area are altered between the operation and storage or non-operation states thereof, thereby improving operability thereof. In the operating state, the first display and the second display are activated to present information. In the non-operation state, only the first display is activated. In the storage state, to minimize the size of the housing, only the indispensable information items such as the remaining battery power and in-service-area designation are presented, thereby facilitating the apparatus to be accommodated in a small space. In the operation state, the housing is elongated such that the distance between the transmitter and the receiver is similar to that between the mouth and the ear of the user to improve the speech quality in the telephone call. Moreover, the display area is increased to possibly present a dial number inputted.
