摘要： There is described an FM receiver (29) including; an antenna (2) able to receive a high frequency signal from a transmitter; a high frequency stage (3); an oscillator (5); a mixer unit (30) able to provide a signal (S6) at an intermediate frequency (fIF); an FM demodulation stage (8); and an automatic frequency control stage (36) able to control the oscillator, so as to keep said intermediate frequency (fIF) of said signal (S6) constant. This receiver further includes a locked loop (32) arranged to enslave said intermediate frequency (fIF) from a pilot frequency (fp) present in the demodulated signal. One advantage of such a locked loop is that the intermediate frequency is enslaved so that the aliasing phenomenon does not prevent demodulation of the signals containing the RDS data.

摘要： A radio carrier signal is detected (20) after being converted to digital form and is filtered (22). A noise estimator (24) generates a noise estimate signal by estimating the noise in the detected signal due to atmospheric conditions and the noise due to the gain in noise figure properties of the circuitry. The output of the noise estimator is used to calculate a threshold signal (50) and another detection operation (52) determines whether the power of a signal derived from the detected signal exceeds the threshold. If the threshold is exceeded, the detected signal is passed through a signal conditioner, such as a switch (54) to an output path (56).

摘要： In a receiver, a tuner (TUN) converts a reception signal (Srf) to an intermediate-frequency signal (Sif). An adjustable frequency converter (AFRC) converts the intermediate-frequency signal (Sif) to an input signal (Sin) for a filter arrangement (FIL) which is capable of providing various frequency responses (Hfil1, Hfil2) associated with different transmission standards. The adjustable frequency converter (AFRC) and the filter arrangement (FIL) may form part of an integrated receiver-circuit (IRC) suitable for many different transmission standards. The tuner (TUN) may provide the intermediate-frequency signal (Sif) at any one of various different intermediate frequencies (IF1, IF2). For any intermediate frequency (IF1,IF2), the adjustable frequency converter (AFRC) can be adjusted in such a way that the filter arrangement (FIL) receives the input signal (Sin) in a frequency range (FR) which is suitably located with respect to its frequency responses (Hfil1, Hfil2). Thus, the adjustable frequency converter (AFRC) allows the use of any one of various different intermediate frequencies and, therefore, allows the use of relatively cheap standard-specific tuners. Thus, it allows relatively cost-efficient implementations.

摘要： A system and method for performing power management in a communication system without losing data is disclosed. The G.Lite system is an exemplary system suitable for implementing the present invention because it includes at least one operational state and an idle state in which no data is transmitted. The G.Lite standard defines ATU states. The defined states are full on state L0, low power state L1 and idle state L3. In L0 state, the ADSL link is fully operational at full data rate. In L1 state, the ADSL link is fully operational at a lower data rate. In L3 state, no signal is transmitted. Because no signal is transmitted, no idle cells are transmitted. This will result in losing the cell delineation and ATM link connectivity. Therefore, when data is received for an ATU in L3 state, data cells may be lost. The present invention solves the problem of lost data cells by allowing interaction between the control path and the data path by requesting that the micro-controller be interrupted when a data cell arrives for an ATU-C that is in L3 state. When a data cell arrives for an ATU-C in L3 state, the micro-controller is interrupted. The micro-controller then ensures that a sufficient number of idle cells are sent to the ATU-C prior to any data cells being sent to the ATU-C.
摘要翻译：公开了一种在不丢失数据的情况下在通信系统中执行电力管理的系统和方法。 G.Lite系统是适用于实现本发明的示例性系统，因为它包括至少一个操作状态和不发送数据的空闲状态。 G.Lite标准定义了ATU状态。定义的状态在状态L0，低功率状态L1和空闲状态L3满。在L0状态下，ADSL链路以全数据速率完全运行。在L1状态下，ADSL链路以较低的数据速率完全运行。在L3状态下，不发送信号。因为没有发送信号，所以不会发送空闲信元。这将导致丢失小区描述和ATM链路连接。因此，当为L3状态的ATU接收数据时，数据信元可能丢失。本发明通过在数据单元到达处于L3状态的ATU-C时，通过请求中断微控制器来允许控制路径和数据路径之间的交互来解决丢失数据单元的问题。当数据单元到达L3状态的ATU-C时，微控制器被中断。然后，微控制器确保在将任何数据信元发送到ATU-C之前，足够数量的空闲信元被发送到ATU-C。

摘要： A method and structure of recovering a network time-base for radio data demodulation after an IDLE period of data communication gauges a local low frequency oscillator versus the high frequency local oscillator to compute the IDLE time as an equivalent number of low frequency oscillator clock periods. Depending upon the high frequency oscillator value, the accuracy of the gauging will directly determine the IDLE period duration versus the gauging period duration in order to keep an acceptable gauging error related to the sampling errors.
