摘要： A mobile terminal can identify cellular control channels that can be received by the mobile terminal from a cellular system, by identifying a cellular control channel that can be received from a history list of cellular control channels that were previously received by the mobile terminal. A next cellular control channel that can be received by the mobile terminal then is scanned for, by skipping at least one cellular control channel that is adjacent the cellular control channel that was identified, based on channel allocation rules in the cellular system.

摘要： Method and apparatus for efficiently suppressing receiver blocking signals and transmitter overtones in a radio transceiver. In an exemplary embodiment, a transceiver includes a transmitter for generating information signals to be transmitted by the transceiver, and a receiver for processing information signals received by the transceiver. A power amplifier connected to an output of the transmitter amplifies information signals prior to transmission, and a low-noise amplifier connected to an input of the receiver amplifies received signals prior to processing. Additionally, a band-pass filter connected to an input of the low-noise amplifier filters received signals prior to amplification. Time-division multiplexing of transmitted and received signals is accomplished by a switch alternately connecting a radio antenna of the transceiver to the output of the power amplifier in the transmit path and to the input of the band-pass filter in the receive path. A bi-directional low-pass filter, situated between the antenna and the switch, is used to filter both transmitted and received information signals. The band-pass filter and the low-pass filter attenuate disruptive receiver blocking signals. The low-pass filter also attenuates unwanted transmitter overtones.

摘要： Method and system are disclosed for preventing phase steps in digital receivers and transmitters that have a controllable gain. The method and system of the invention reduces the number of gain changes by applying hysteresis to the gain control of the receiver or transmitter. For a receiver, the hysteresis is applied with respect to the signal level received at the detector/demodulator. For a transmitter, the hysteresis is applied with respect to the transmit signal level. The hysteresis limits how frequent the gain changes occur so that only signals with amplitudes that exceed or fall below predefined thresholds will trigger a gain adjustment. Small, incremental changes in signal amplitude that lie within the range of the hysteresis will not trigger a gain adjustment.
摘要翻译：公开了用于防止具有可控增益的数字接收机和发射机中的相位步骤的方法和系统。本发明的方法和系统通过对接收器或发射器的增益控制施加滞后来减小增益变化的数量。对于接收机，相对于在检测器/解调器处接收到的信号电平应用迟滞。对于发射机，相对于发射信号电平应用迟滞。滞后限制了增益变化的频率发生，因此只有幅度超过或低于预定阈值的信号才会触发增益调整。位于滞后范围内的信号幅度的小的增量变化将不会触发增益调整。

摘要： A communication device has a controller operatively connected to at least a first transceiver and a second transceiver, wherein the first transceiver receives signals on one or more channels within a first frequency band and the second transceiver transmits signals on one or more channels within a second frequency band, wherein the first and second frequency bands are adjacent one another so that each of the first and second frequency bands has an adjacent border and a nonadjacent border. Coexistence between the first and second transceivers is achieved by adjusting receive and/or transmit filters associated with the transceivers to create a guard band that is located more in the first frequency band if the second transceiver is using frequencies close to its adjacent border, and a guard band that is more in the second frequency band if the second transceiver is not using frequencies close to its adjacent border.
摘要翻译：通信设备具有可操作地连接到至少第一收发器和第二收发器的控制器，其中第一收发器在第一频带内的一个或多个信道上接收信号，并且第二收发器在第二频率内的一个或多个信道上发送信号带，其中所述第一和第二频带彼此相邻，使得所述第一和第二频带中的每一个具有相邻边界和不相邻的边界。通过调整与收发器相关联的接收和/或发射滤波器来实现第一和第二收发器之间的共存，以产生更靠近第一频带的保护频带，如果第二收发器使用接近其相邻边界的频率，以及如果第二收发器不使用靠近其相邻边界的频率，则在第二频带中更多的保护频带。
