    • In a mobile communications system each radio unit (14,16) is associated with a respective base station (12) as its `home` base station; any radio unit can communicate with any base station in whose service area it is located. Each base station has a radio interface (20) for communication with radio units, a telephone interface (24) for connection to a telephone line, for example via a PABX (44), and a LAN interface (28) for connection to a local area network (40) to which all the base stations are coupled. Voice communications for a handset are always routed through the home base station for that handset, e.g. to another handset or to the PABX, irrespective of the identity of the base station in whose service area the handset is currently located.

    • A system, including a data regenerator, for converting split phase Manchester encoded binary data into NRZ data and for generating clock pulses which are synchronized with the NRZ data is disclosed. MOS FETs are used throughout the system. The data regenerator includes two transition detectors which detect logic 0 level to logic 1 level transitions in the split phase Manchester encoded data and in its complement, and produce pulses in response to the detected transitions. The data regenerator also includes four gates which are controlled by the output of a delay unit. The delay unit is activated by the output of a bit time pulse generator, which responds to the outputs of two of the four gates. When the gates are enabled, a pulse from a transition detector passes through one of these two gates to the bit time pulse generator, causing the latter to produce a pulse which activates the delay unit. The total delay provided by the pulse generator and the delay unit is such that the output of the delay unit disables the gates for at least 1/2 bit period, after which the gates are again enabled to respond to a subsequent pulse from one of the detectors. The pulse generator thus provides a sequence of pulses which are synchronized with mid bit time transitions in the Manchester encoded data. Output pulses from one of the other two of the four gates are applied to the set input to a flip-flop, while the output pulses from the other of these two gates are applied to the reset input to the flipflop, the output of which represents the regenerated NRZ data.
    • 公开了一种包括数据再生器的系统,用于将分裂相位曼彻斯特编码的二进制数据转换成NRZ数据并产生与NRZ数据同步的时钟脉冲。 在整个系统中使用MOS FET。 数据再生器包括两个转换检测器,它们在分相曼彻斯特编码数据及其补码中检测逻辑0电平到逻辑1电平转换,并响应于检测到的转换而产生脉冲。 数据再生器还包括由延迟单元的输出控制的四个门。 延迟单元由比特时间脉冲发生器的输出激活,该脉冲发生器响应四个门中的两个的输出。 当门被使能时,来自转换检测器的脉冲通过这两个门中的一个到位时间脉冲发生器,导致后者产生激活延迟单元的脉冲。 由脉冲发生器和延迟单元提供的总延迟使得延迟单元的输出使至少1/2位周期的栅极禁用栅极,此后门再次使能以响应来自其中一个的后续脉冲 探测器 因此,脉冲发生器提供与曼彻斯特编码数据中的中间位时间转换同步的脉冲序列。 来自四个门中的另外两个的输出脉冲被施加到触发器的设置输入,而来自这两个门中的另一个的输出脉冲被施加到触发器的复位输入,输出 其代表再生的NRZ数据。

    • In a radio paging system each pager includes a timer having a clock to provide date and time stamping of received messages. To set the time of the pager clock, the system base station transmits time message signals at regular intervals but which are of variable accuracy due to delays in signal formatting and propagation. The invention provides a pager wherein a control unit sets the timer clock in accordance with the time indicated by a transmitted time message signal which is determined to be the most accurate, such signal being selected as a time reference signal. The most accurate signal is determined by comparing the differences in indicated times of transmission and reception of an already selected current time reference signal with those of a presently received time message signal. If the presently received time message signal is the more accurate, it is substituted as a new time reference signal in place of the current time reference signal.

    • A system for carrier synchronization in a multi-phase transmission system of synchronous pulse signals in which the multi-phase modulator at the transmitter end and the multi-phase demodulator at the receiver end are provided with orthogonal modulators. In order to recover the carrier at the recover end in the correct phase position under all circumstances while avoiding phase uncertainties, a clock interval is reserved for the transmission of a synchronizing signal which is transmitted at the transmitter end through a first channel of the orthogonal modulator while simultaneously the second channel of the orthogonal modulator is interrupted. For the local carrier recovery the receiver comprises a phase stabilization channel connected to the output of the modulator in the receiver channel corresponding to the second transmission channel, which stabilization channel incorporates a blocking circuit which for the purpose of phase stabilization is released by a switching signal at the synchronizing intervals originating from a synchronizing interval selector which for the purpose of selecting the synchronizing intervals of lower signal level is fed by the received phasemodulated oscillations.
