Title: Mobile radio equipment having frequency stabilizing function
Inventor: FUTAKATA TOSHIYUKI
IPC: H04B1/10
Filed: 1993-03-04
Abstract: PURPOSE:To follow a frequency of a reference oscillator with a reception frequency and to make the frequency stable even when a phase rotation of pi/4 or over is in existence in one-symbol Ts. CONSTITUTION:A phase quantization means 25 detects a phase of a received intermediate frequency signal for each Ts/2 and a delay means 27 gives a delay of Ts and Ts/2 to the detected phase data. A phase change detection means 31 obtains a phase difference between current phase data phi(to) and Ts delay phase data phi(to-Ts) and a phase rotation detection means 32 detects a phase rotation direction of a received modulation wave based on the polarity of a difference between the data phi(to-Ts) and the Ts/2 delay phase data phi(to-Ts/2). A frequency error signal generating means 33 obtains a correct phase rotation error based on the detected phase difference and phase rotating direction and an oscillating frequency of a reference oscillator is controlled so as to reduce the error.

Abstract: PURPOSE:To attain the use of a crystal having low frequency stability by using a crystal oscillator for transmitting and receiving a pilot signal in common at the transmission/reception section in an earth station transceiver using a pilot signal and correcting automatically the transmission frequency. CONSTITUTION:An earth station transmission section Tx is provided with a pilot signal oscillator 5 and the reception section Rx is provided with a pilot receiver P oscillating the frequency in response to the frequency fluctuation of the said pilot signal returned via a satellite SAT. The pilot receiver P includes a voltage controlled oscillator 19 and its oscillated output is inputted to a phase synchronizm oscillator 4 of the transmission section Tx as a reference frequency. The pilot signal oscillator 5 and the reference crystal oscillator 7 of the pilot reciever P are used in common. As a result, since the output frequency of the receiver P is made independent of the frequency fluctuation of the crystal oscillator 7, the crystal oscillator 7 with low frequency stability is used.

IPC: H03K5/13
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a variable pulse width circuit in which both a pulse width and a phase of a pulse are adjusted. SOLUTION: When a level of an input pulse signal Sin changes from 'L' to 'H', an NMOS 26 is conductive to make a current path I2 conductive, and when the level of the signal Sin changes from 'H' to 'L', an NMOS 22 is conductive to make a current path I1 conductive. The signal Sin is given to a buffer 31 via the current path I1 or I2. A signal propagation delay time in each of the current paths I1 and I2 is set by a resistance of transfer gates 21, 25 that change with control signals SI1, SI2 respectively and the capacitance of a capacitor 24. Thus, a propagation time of the leading edge and the trailing edge of the signal Sin is individually controlled through the adjustment of the control signals SI1, SI2, and both a pulse width and a phase of an output pulse signal Sout are controlled.
