  • Patent number: 5850601
    Abstract: A cordless telephone apparatus has a base station connected to a public telephone network and assigned with a specific identification code and one or more personal stations linked to the base station through the medium of radio frequencies. The base station has one or more additional functions in addition to the speech function. The personal station can perform radio communications with the base station within a range in which radio waves from the base station is receivable and can perform radio communications with a cell station connected to a public telephone network outside the radio wave receivable range. The personal station has a remote-control instruction unit for instructing operation of the additional function of the base station.

  • Patent number: 5696792
    Abstract: The number of oscillators required to construct a digital radiocommunication terminal can be reduced and a circuit used for the digital radiocommunication terminal can be reduced in size. For this purpose, the digital radiocommunication terminal for effecting information transmission using an N (integer)-phase-shift-keyed signal (identification symbol number N=4 upon .pi./4 shifted QPSK modulation), is constructed such that an oscillation frequency generated from a reference oscillator employed with a frequency synthesizer is selected to have a common multiple of a second intermediate frequency and an identification symbol phase N and is supplied to a detector for outputting received data therefrom.
