Abstract: This invention is directed to a wireless apparatus to carry out transmission and reception by either a digital communication system or an analog communication system and, in particular, provides a technical method to change over a signal system for a transmission electric wave. Concretely, when a carrier is received, a switch (PTT) is pushed in the case of response. In this case, if a default set transmission signal system is different from a reception signal system of a received audio signal, it is possible to modulate the audio signal after the transmission signal system is changed over to the same signal system as the reception signal system. Thus, a wireless apparatus is provided for making it possible to promptly change over a signal system of a transmission electric wave without doing troublesome operations.

Abstract: A soft decision device and method for obtaining a soft decision value as a value expressing a probability as near the actual probability as possible by simple processing. The soft decision device and method are used to output a soft decision value for each bit of each symbol used for decoding the each symbol as a value corresponding to the function value obtained by applying a predetermined function for each bit to the sampled value of the each symbol according to the demodulated signal such that the probability distribution of the sampled value in each symbol point is the Gauss distribution. The function for each bit is approximated to a curve expressing the probability that each bit is 1 or 0 for the sampled value of each symbol of the demodulated signal and defined by using a quadratic function.

Abstract: Information, which has a frame structure and is to be transmitted from a line control apparatus (101) through a control channel to a mobile transmitting/receiving apparatus (102), includes function channel identifying information indicative of the type of information transmitted in an area of control information. When no message is existent which must be notified to the mobile transmitting/receiving apparatus (102), the line control apparatus (101) establishes an idle message in the area of control information and also establishes the function channel identifying information, which is in the same frame, as idle identifying information. If the function channel identifying information is the idle identifying information, the mobile transmitting/receiving apparatus (102) switches a receiving operation in the area of control information into a reception stop operation. Otherwise, the mobile transmitting/receiving apparatus (102) continues the receiving operation in the area of control information.

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: An optical pickup device enables prevention of an increase of spherical aberration during tracking without needing any finite optical system. The diameters of parallel light beams (A, B, C) for the next-generation DVDs, DVDs, and CDs are limited to diameters of a, b, c (a>b>c) in accordance with the NA for each type by a light beam limiting element, the diameter of light beam B is limited to the diameter ranges of b to c and d (=0.85×c) to e (d>e>0), the diameter of the light beam C is limited to the diameter ranges of c to d and less than e. They are passed through a phase correcting element (13B) and focused on the corresponding optical recording medium signal planes by means of a common objective lens. The objective lens is so optimized that the wave front aberration to the light beam A is minimum on the signal plane of the next generation DVD.

Abstract: A signal connecting method and apparatus is provided which can reduce noises and create natural synthesized voices. The signal connecting method (or apparatus) for connecting a plurality of waveform signals and creating a synthesized waveform signal, has: a step (or unit) for determining an upper limit frequency of a frequency spectrum of each of the plurality of waveform signals; and a step (or unit) for filtering at least a connection portion of each waveform signal by using predetermined filter characteristics having the determined upper limit frequency. The cut-off frequency of the filtering is the higher upper limit frequency in upper limit frequencies of spectra of adjacent two waveform signals before and after the connection portion of the waveform signals. Higher harmonics to be caused by discontinuity of the connection portion of waveform signals can be effectively removed and noises of synthesized waveform signals can be reduced considerably.

When displaying a map screen and an existing facility icon on a display unit (22), it is judged whether the facility information table (252) contains facility icon information having coordinate information contained within a range indicated by the map screen. If YES, the corresponding facility icon is overlay-displayed on the map screen and the existing facility icon.

Abstract: An encoder encodes sound 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 shaped. 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.
