    • A work flow manager (1) of a gateway comprises a process automation component (2), a policy engine (3), and a traffic gateway (4). The work flow manager (1) communicates via the internet (5) over IP with content providers (6) and content aggregators (7). On the other side it communicates over the Internet or over a private IP network, using diverse proprietary and known protocols with service enabler resources (20) including mobile network SMSCs, MMSCs and IMSs (IP Multi-Media Sub-systems). The process automation component (2) presents a GUI to generate a work flow definition in a high level business process execution language (BPEL), with interaction with the service enabler resources (20) which implement the process. The policy engine (3) interprets the BPEL to provide lower-level policy enforcement work, flows in a policy enforcement execution language (PEEL). The traffic gateway (4) interprets the PEEL to provide a low level language (traffic policy execution language, TPEL) for high performance implementation of steps of the work flow process. PRP means Policy Request Protocol, a lightweight protocol for AAA request/responses within the gateway 1.
    • 网关的工作流管理器(1)包括过程自动化组件(2),策略引擎(3)和业务网关(4)。 工作流程管理器(1)经由互联网(5)通过IP与内容提供者(6)和内容聚合器(7)进行通信。 另一方面,它通过互联网或专用IP网络进行通信,使用各种专有和已知的协议与包括移动网络SMSC,MMSC和IMS(IP多媒体子系统)的服务使能器资源(20)进行通信。 过程自动化组件(2)提供GUI,以在高级业务流程执行语言(BPEL)中生成工作流定义,与实现该过程的服务使能器资源(20)进行交互。 政策引擎(3)将BPEL解释为提供较低级别的策略执行工作,以策略执行执行语言(PEEL)流动。 交通网关(4)解释PEEL提供低级语言(交通策略执行语言,TPEL),用于高性能实施工作流程的步骤。 PRP意味着策略请求协议(Policy Request Protocol),用于在网关1内进行AAA请求/响应的轻量级协议。

    • A smart external antenna module is proposed for wireless systems. The module allows the advantages of smart antennas to be easily added to existing wireless systems without any modification to the transceiver. Specifically, the smart antenna module weights and combines the signals received by multiple antennas to improve the received signal quality, and then when it detects that there is a signal to be transmitted by the transceiver, it turns off the receiver, turns on the transmitter and uses the receive weights to transmit the signal out of the multiple antennas to improve signal reception at the desired user. Such a module can be added to the external antenna port of an existing transceiver with no change to that transceiver.
    • 为无线系统提出了一种智能外部天线模块。 该模块允许将智能天线的优点轻松添加到现有的无线系统中,而无需对收发器进行任何修改。 具体地说,智能天线模块对由多个天线接收到的信号进行权重并组合以提高接收信号质量,然后当它检测到有收发信机要发送的信号时,它关闭接收机,打开发射机, 使用接收权重从多个天线发送信号以改善在期望用户处的信号接收。 这样的模块可以添加到现有收发器的外部天线端口,而不改变该收发器。

    • An active circuit includes (a) a first chopper circuit that receives an input signal and a chopping signal of a frequency higher than a base band of the input signal, and that provides a modulated input signal; (b) an amplifier that receives the modulated input signal and that provides an amplified signal resulting from amplifying the modulated input signal; and (c) a second chopper circuit that receives the amplified signal and the chopping signal to provide an output signal. The chopping signal has a frequency that may be dynamically adjusted to accommodate changes in impedance and signal spectrum as a result of the operations of the chopper circuits. The active circuit further includes a low pass filter that receives the output signal and that attenuates components of the output signal above the base band of the input signal. In this manner 1/f noise introduced by the amplifier is eliminated or reduced.
    • 有源电路包括:(a)第一斩波电路,其接收输入信号和高于输入信号的基带的频率的斩波信号,并提供调制输入信号; (b)放大器,其接收经调制的输入信号并提供由放大经调制的输入信号产生的放大信号; 和(c)接收放大信号和斩波信号以提供输出信号的第二斩波电路。 斩波信号具有可以被动态调节的频率,以适应由于斩波电路的操作而导致的阻抗和信号频谱的变化。 有源电路还包括低通滤波器,其接收输出信号并且衰减输入信号的基带上方的分量。 以这种方式消除或减少由放大器引入的1 / f噪声。
