Abstract: In a navigation device, a destination waypoint is set by a user through an input section (13), and, when guidance to the destination waypoint is started, a control section (11) stores positional information on the destination waypoint into a destination waypoint history table (21) of a storage section (12) at predetermined timing, the destination waypoint history table (21) storing positional information on destination waypoints. Stored information is displayed on a display section (14) when the user sets a destination waypoint. The user can select a destination waypoint based on the displayed information and set the destination waypoint. After the destination waypoint is set, only the destination waypoint satisfying predetermined conditions is stored.

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: Even when digital media of the respective devices are not media of common codec, the digital media can be reproduced in other device. A digital medium is provided to a providing destination device which reproduces the digital medium upon receiving it. Before providing the digital medium, a codec which can be used in the providing destination device is reported to the providing source device (step 22). The provision of the digital medium is directly performed without performing conversion if the codec is a predetermined common codec. If the codec is not the common codec, it is converted into a medium format of the common codec. Alternatively, if the codec can be used by the providing destination device, the codec is directly used in the medium format (steps 23-26).

Abstract: There is disclosed a base band signal generation device and others for processing transmission data so that a reception side can restored the data without recognizing whether the data has been subjected to a processing and transmitting the data with an appropriate efficiency corresponding to the communication quality. A transmission device T judges the communication quality of a transmission path L. When the communication quality is preferable, a four-value FSK symbol is generated from the bit of the most significant part of the encoded voice data and the bit of the least significant part. When the communication quality is not preferable, a four-value FSK symbol is generated from the bit of the most significant part of the encoded voice data and a redundant bit of “0”. However, a symbol containing a redundant bit is set to the maximum value or the minimum value of the four values which the symbol value may have.

Abstract: Reception timing of a signal consisting of a valid symbol section and a guard interval section is controlled properly. According to a result of auto-correlation calculation performed by a guard correlation processor, a timing adjustment block generates a control voltage for adjusting the reception timing of the valid symbol section. A first and a second loop filter filter the control voltage signal generated by the timing adjustment block and sends it to a switch. An inter-symbol interference decision block decides whether an inter-symbol interference is generated according to the result of the auto-correlation calculation performed by the guard correlation processor, and controls the switch according to the decision result. Where, in the first loop filter, a comparatively large gain is set while in the second loop filter, a comparatively small gain is set.

Abstract: A frequency interpolation apparatus is provided which reproduces a signal similar to an original signal by approximately recovering suppressed frequency components, from an input signal having the suppressed frequency components in a specific frequency band of the original signal. The input signal is divided into a plurality of signal component sets each having frequency components in a frequency band among a plurality of frequency bands, and a signal component set in the band with the suppressed signal components is synthesized from the plurality of divided signal component sets and added to the input signal. Each of the plurality of divided signal component sets is frequency-converted to a signal component set in the same frequency band, and the signal component set in the band with the suppressed signal components is synthesized through linear combination of the frequency-converted signal component sets.
