Abstract: The present invention relates to a radio communication trunking system control method. According to the control method, a channel (f1), which is normally used as a control channel, is used as a telephone communication channel when a plurality of channels (f2-fn), used as telephone communication channels, are being used. For example, the channel (fn) has been adapted to be able to operate not only as a telephone communication channel but also as a control channel. When the telephone communication using the channel (fn) is completed, the channel (fn) is established as a control channel in place of the channel (f1). In this way, the currents consumed by wireless units accommodated in a trunking system can be reduced, and the time period for which the trunk operation is inoperative can be significantly reduced.

Abstract: A frequency interpolating device for restoring a signal similar to the original signal by creating a suppressed frequency component of a specific frequency band of the original signal, approximately from the input signal having the suppressed frequency component. In the frequency interpolating device, when the suppressed frequency component is artificially created from the input signal and added to the input signal, the additional level is set dynamically and adaptively on the basis of the spectrum pattern of the remaining frequency component of the input signal. This setting of the addition level is done by searching a look-up table which stores data that causes a plurality of reference frequency spectrum patterns to be associated with predetermined addition levels. Moreover, the data stored in the table is created on the basis of the results of either an aural test on a plurality of signal sample sounds or a physical frequency analysis on the massive signal data.

Abstract: A vehicle (12) starts from the front of a home (11a) and moves to a destination (11b). An area (area—1) with the home (11a) at the center is an area where the position of the home (11a) is estimated to be easily specified, and a road (13a) to be searched is a road required for searching a moving route of the vehicle (12). An in-vehicle device (200) does not transmit position information or the like acquired in the area (area—1) in response to a request of position information from a road side device (100). The in-vehicle device (200) transmits the position information or the like on the vehicle (12) acquired after the vehicle (12) moves out of the area (area—1) to the road side device (100). The position information on the vehicle is transmitted to the road side device by protecting personal information.

Abstract: A voice signal interpolation apparatus is provided which can restore original human voices from human voices in a compressed state while maintaining a high sound quality. When a voice signal representative of a voice to be interpolated is acquired by a voice data input unit 1, a pitch deriving unit 2 filters this voice signal to identify a pitch length from the filtering result. A pitch length fixing unit 3 makes the voice signal have a constant time length of a section corresponding to a unit pitch, and generates pitch waveform data. A sub-band dividing unit 4 converts the pitch waveform data into sub-band data representative of a spectrum. A plurality of sub-band data pieces are averaged by an averaging unit 5 and thereafter a sub-band synthesizing unit 6 converts the sub-band data pieces into a signal representative of a waveform of the voice by a sub-band synthesizing unit 6.

Abstract: An encoder encodes audio data and the like to generate a binary signal. A mapper converts the binary signal into a four-level symbol and outputs the four-level symbol. A base band filter includes a root raised cosine filter and a sinc filter. The base band filter blocks a predetermined frequency component of a symbol to shape the symbol into a waveform signal and outputs the waveform signal shape. An FM modulator transmits a signal subjected to FM modulation according to a magnitude of an amplitude of a waveform signal to a receiving unit. When a symbol of ±3 is outputted from the mapper, a frequency shift of a signal transmitted from the FM modulator has a predetermined value in a range of ±0.822 [kHz] to ±0.952 [kHz]. This makes it possible to provide a modulating apparatus, a mobile communication system, a modulating method, and a communication method that use a modulating method that can conform to the FCC rule to be enforced in 2005 without using a linear power amplifier.

Abstract: The present invention provides a speech signal compression device which allows a storage capacity of data representing speech to be efficiently compressed. In the present invention, a computer C1 operates with respect to speech data to be compressed into speech data for each phoneme on the basis of phoneme labeling data, to unify the time length of a unit pitch section for each of the divided speech data into the same value, thereby creating a pitch waveform and creating a sub-band data representing variation in time of spectrum components of the pitch waveform signal. Also, this sub-band data is compressed so as to match a condition designated by a table for compression, and the compressed data is further encoded in entropy to output the entropy coded data.

Abstract: Both a pre-word (PW) and a sync word (SW) are used to establish a synchronization or only the sync word (SW) is used to establish a synchronization in accordance with an operational status related to the synchronization in a mobile wireless communication apparatus. For example, during an initial synchronization with a control channel (110) being received, both the pre-word (PW) and the sync word (SW) are used to establish a synchronization when a calculation result in a synchronization calculating part exceeds a predetermined threshold value only once. During an initial synchronization with a direct communication channel (112) being received, both the pre-word (PW) and the sync word (SW) are used to establish a synchronization when the calculation result exceeds the predetermined threshold value once; or alternatively, only the sync word (SW) is used to establish a synchronization when the calculation result successively exceeds the predetermined threshold value twice.

Abstract: An effective random access control can be performed with a high throughput. A base station (11) communicates with mobile stations (12) by use of slotted ALOHA system. An offset time of 1.5 frames is established between upstream and downstream communication frames. If any of the upstream communication frames is available, the base station (11) notifies a transmission permission signal (I) by use of the corresponding downstream frame. If having data to be transmitted, a mobile station (12) in a reception state receives the transmission permission signal (I), switches itself into a transmission state, and transmits one frame of leading data by use of the upstream frame. If permitting continuous transmission of data following the leading data, the base station (11) transmits a continuous transmission permission information (P) to that mobile station (12), and transmits a transmission inhibition signal (B) to the other mobile stations (12) during that continuous transmission.

Abstract: There are provided a transmission and reception device having a function for correcting a data error in a communication path. In the transmission device, a redundant bit addition unit adds a redundant bit to each data bit which has been divided by one bit by a division unit; and an interleaver performs interleave. The transmission device transmits a signal which has been subjected to FM modulation by an FM modulation unit. In the reception device, a symbol decision unit performs a symbol decision at a Nyquist point for a signal which has been FM-demodulated by an FM demodulation unit; a bit conversion unit performs bit conversion according to the result of symbol decision; and a frame recovery unit deletes the redundant bit added by the redundant bit addition unit of the transmission device, from the bit string de-interleaved by a de-interleaver. Thus, it is possible to surely perform an error correction with a simple configuration even when the communication state is not in a preferable environment.
