摘要： In a cellular radio communications system:
(i) at least one signal comprising control channel information is broadcast on a carrier to subscribers within the cellular radio communications system;
(ii) the said carrier is divided into TDMA frames, each TDMA frame having a frame number (N);
(iii) the system is adapted to store at least two sets (S0-S2) of pre-determined frequencies (f i ), the said carrier being broadcast at any particular time on a frequency taken from a selected one of the said sets (S0-S2) of pre-determined frequencies (f i );
(iv) the system is adapted to chose the said selected one of the said sets of pre-determined frequencies (f i ) in dependence on the frame number (N) of the TDMA frame being broadcast at the said time.
The invention allows the radio system to employ both frequency hopping and multi-slot transmission, for example in an EDGE compact GSM system.摘要翻译： 在蜂窝无线电通信系统中：（i）包括控制信道信息的至少一个信号在载波上广播到蜂窝无线电通信系统内的用户; （ii）所述载波被划分成TDMA帧，每个TDMA帧具有帧号（N）; （iii）所述系统适于存储预定频率（fi）的至少两组（S0-S2），所述载波在任何特定时间以从所选择的所述组中选择的频率（S0 -S2）预定频率（fi）; （iv）所述系统适于根据在所述时间正在广播的TDMA帧的帧号（N）来选择所述所述预定频率组（fi）中的所选择的一个。 本发明允许无线电系统采用跳频和多时隙传输，例如在EDGE紧凑型GSM系统中。

摘要： The invention relates to a radio communication system in which a time slot of a frame of a multiframe signal allocated to the frequency control channel is modulated using an 8PSK modulation scheme to contain a tone having a frequency which GMSK modulation is unsuited to generate. This enables COMPACT-format signals to be distinguished from GSM - format signals and ensures backwards compatibility with all existing GSM mobile stations.
摘要翻译： 本发明涉及一种无线电通信系统，其中使用8PSK调制方案调制分配给频率控制信道的多帧信号的帧的时隙以包含具有不适于生成GMSK调制频率的音调。 这使得COMPACT格式信号可以与GSM格式信号区分开，并确保与所有现有GSM移动台的向后兼容性。

摘要： A security system for actuating a security mechanism of a vehicle includes a transceiver coupled to the security mechanism and having one transmission channel for transmitting a first signal and a number of reception channels. A remote radio-frequency transponder key has a number of transmission channels (320, 322, 324; 330, 332, 334) and one reception channel matched to the respective reception and transmission channels of the transceiver. The transponder key is arranged to transmit an unlock signal to the transceiver upon reception of the first signal. The unlock signal is verified by the transceiver as valid before actuating the security mechanism. The transceiver is further arranged to select a channel for reception of the unlock signal and to embed the identity of the selected channel in the first signal (210), such that the transponder key transmits the unlock signal using the selected channel.

摘要： A control circuit (52) for controlling power supplied to an igniter element (54), comprises a first input (70) for receiving an encoded input signal generated in response to the initiation of a firing mode or a diagnostic mode. The encoded input signal comprises a code portion (100) having at least two pulses, and a power portion (102). Logic circuitry (74) determines whether the code portion (100) is valid, the code portion (100) being determined valid when it meets predefined conditions within a predetermined time window, and provides an unlocking signal (Sfire) at an output (76) when the code portion (100) is determined to be valid. A switch (78), which has a control input coupled to the output (76) of the logic circuitry (74), is enabled on receipt of the unlocking signal so that power, including the power portion (102) of the encoded input signal, at the first input (70) of the control circuit (52) is supplied to the output of the switch for energising the igniter element (54). In the firing mode the power supplied via the enabled switch fires the igniter element (54).
