摘要： A personal mobile communications system comprises base stations (4-1.about.4-4) located in respective zones and a paging station (8) covering an area including the zones, or cells (5-1.about.5-4). The paging station and all base stations are connected to a public switched telephone network (PSTN). When a call is originated from a PSTN user (2) to a mobile user (10), the paging station receives a call-setup request from the PSTN containing the address codes of both PSTN and mobile users, and broadcasts the call-setup signal over the covered cells. One or more base stations (4-1.about.4-3) receive the call-setup signal and, in response, broadcast an alert signal. One of the base stations (4-2) receives an off-hook signal from the alerted mobile station (10) and dials the PSTN user address code contained in the call-setup signal to the PSTN to establish a connection (15; 147.about.149; 176.about.178) between the calling and called parties (2,10).

摘要： A privacy code-type signal transmission system includes a transmitter having a signal sampler for producing analog samples of an analog audio signal, an analog to digital converter, a scrambler, a multi-level analog former and modulator means. The analog to digital converter converts each analog sample into a parallel n bit digital signal. The parallel n bit digital signal is scrambled by a digital scrambler to produce a second parallel n bit digital signal. The second n bit digital signal is input to a multi-level former having 2.sup.n different levels, the output of which is a 2.sup.n level analog signal which is suitably modulated for transmission to a receiver. The receiver demodulates the 2.sup.n level analog signal and with a level discriminator converts the demodulated signal to a scrambled digital signal corresponding to the scrambled digital signal produced at the transmitter. The original analog audio signal is then recovered by descrambling the digital signal and applying the descrambled digital signal to a digital to analog converter. This system eliminates any need for parallel-serial and serial-parallel converters, as well as frame sync insertion and extraction circuits necessary in conventional privacy code-type transmission systems.

摘要： Waveform converting circuits are disclosed which eliminate errors in data reproduction due to the transitional response of low or high pass filters even if the data signal contains a D.C. component. The converting circuits have a comparator with first and second input terminals. The comparator produces a "1" or "0" output depending on the comparison of the voltages of input signals fed to these first and second input terminals. In one type of converting circuit, a low pass filter is connected between the signal input terminal and the second input terminal of the comparator, while the signal input terminal is directly connected to the first input terminal of the comparator. A feedback circuit including a low pass filter is connected between the output and the second input terminals of the comparator. In another type of converting circuit, a high pass filter is connected between the signal input terminal and the first input terminal of the comparator, and a limiter is connected to the output of the high pass filter. A feedback circuit is provided between the output and either the first or second input terminals of the comparator.

摘要： Responsive to several signal bits carrying an information piece and received with inevitable fluctuations of the signal bit widths and height, a time diversity receiver reproduces the information piece by mainly taking the widest or highest signal bit into consideration. In order to give significance to the widest or highest signal bit, the signal bit levels are added for each information piece. When high-frequency pulses are used to derive the sum width of the signal bit widths, it is preferred to substitute pulses of a frequency equal to a half or so of the high frequency for the high-frequency pulses representative of the width of the signal bit or bits received with serious fluctuations. Alternatively, the transmitter carries out the reproduction by attaching importance to the signal bit received with smallest fluctuations either solely or together with the preference or weight put on the widest or highest signal bit.

摘要： A CDMA radio wave signal is transmitted at a first place (a base station). A mobile unit receives the first CDMA radio wave signal and stores at least a portion of the data in the received signal and returns it to the base station by attaching the portion of the data to the second data to be transmitted through spectrum spreading, wherein the data rate of the attached data is higher than the second data. The base station detects an upward line transmission quality from the received second CDMA radio wave signal from the mobile unit, the downward line transmission quality is measured in the mobile station and the data of the downward line transmission quality is attached in place of forwarded data. When a downward line transmission quality is lower than a reference, the data is retransmitted from the base station and for a predetermined interval in this condition, transmission is stopped as transmission controlling. Corresponding base and mobile stations are also disclosed.

摘要： A noise detection circuit for a digital radio receiver comprises a sampling circuit for sampling a digital baseband signal having a noise component when an eye opening of the baseband signal is largest. A waveform generator is connected to the output of the sampling circuit for generating a waveform which is a replica of the baseband signal and free from the noise component. The waveform generator comprises a threshold comparator having decision thresholds and a waveform recovery circuit which includes a resistor, a plurality of storage capacitors of equal values and a switch responsive to the output of the threshold comparator for selectively coupling the output of the sampling circuit through the resistor to the storage capacitors. A substractor is connected to the outputs of the sampling circuit and the waveform generator for generating a signal representative of the noise component of the baseband signal. The output of the subtractor circuit can be used for various purposes including noise measurement, squelch action and automatic local oscillator frequency control.

摘要： A digital signal repeater system, including means for controlling the transmitter of the system. The system is substantially immune to fading, interference and noise, and rapidly detects the reception of a digital signal. A first level detector outputs a logical 1 signal to indicate reception of a signal, in response to the level of the IF signal in the receiver. A second level detector indicates when the received signal is digital by filtering the demodulated received signal and generating a logical 1 output when the received signal has a substantial component at a predetermined clock frequency. The two logical output signals are applied to an AND gate and the output is smoothed and compared by a comparator to a reference level. The output of the comparator is used to control the transmitter. In another embodiment, a third level detection circuit determines whether the clock frequency signal has been detected for a comparatively long period of time and, if so, lowers the reference level supplied to the comparator to stabilize its output.

摘要： A squelch signal generator is responsive to a digital input signal (IN) which causes a display of an eye pattern in an oscillascope. The pattern has at least one eye at each time instant appearing at a predetermined period. A squelch threshold level (V.sub.S) is preselected outside of a predetermined one of uppermost and lowermost cross-points of at least one eye. The squelch comparator compares an input level of the input signal with the first squelch threshold level to produce a resultant signal which is representative of a first result of the comparison. The resultant signal is processed at each time instant by a processing circuit into a squelch signal when the input signal is classified into an undesired signal. An additional squelch threshold level may be preselected outside of the other of the uppermost and the lowermost cross-points.
