摘要： A novel power-controlled random-access method allows a mobile station to gain fast access to the base station. At the mobile station, a composite power control command is devised after an initial access attempt. The determination of the composite command uses an open-loop power-control symbol and a closed-loop power-control symbol, to decide the action of the mobile station upon transmission of its next random-access signal. In the preferred embodiment, the composite power control command can specify different levels of increase or decrease in transmission power, and the composite power control command can specify a back-off by the mobile station. This composite power-control mechanism can help resolve collision between mobile stations accessing the same random access sub-channel and therefore maintain a low-delay in the random-access process and a high-utilization on the access-channel resource.

摘要： A method for controlling transmit power of a node in wireless network, such as, e.g., an ad-hoc wireless network operating in accordance with a carrier sense multiple access (CSMA) protocol and where asymmetrical radio links may exist. During a request to send (RTS) and clear to send (CTS) exchange between a first node and a second node, both a request to send (RTS) packet and a probing request to send (PrRTS) packet are transmitted from the first node to the second node. The transmit power and data rate of the PrRTS packet may be different from the transmit power and data rate of the RTS packet. In response, the second node returns a CTS packet that includes a signal to noise ratio (SNR) for both the RTS packet and the PrRTS packet. A correction factor for data transmit power is then computed based in part on both the SNR for the RTS and the SNR for the PrRTS, and a data packet is thereafter transmitted at a power level that has been modified in accordance with the correction factor. The correction factor may further aid the estimation of the signal-to-noise-and-interference ratio (S/(N+I)) at a receiving node, which enables a sending node either to overcome the interference by adjusting the transmit power or avoid the interference by not accessing the channel until it hears the node again.
摘要翻译：一种用于控制无线网络中的节点的发射功率的方法，例如根据载波侦听多路访问（CSMA）协议操作的自组织无线网络，以及其中可能存在不对称的无线电链路。在第一节点和第二节点之间发送（RTS）和清除发送（CTS）交换的请求期间，发送请求（RTS）分组和发送请求（PrRTS）分组都从第一节点到第二个节点。 PrRTS分组的发射功率和数据速率可能与RTS分组的发射功率和数据速率不同。作为响应，第二节点返回包括RTS分组和PrRTS分组的信噪比（SNR）的CTS分组。然后部分地基于RTS的SNR和PrRTS的SNR来计算数据发射功率的校正因子，然后以已经根据校正因子修改的功率电平发送数据分组。校正因子可以进一步有助于估计接收节点处的信噪比干扰比（S /（N + I）），这使得发送节点能够通过调整发射功率来克服干扰，避免在不再访问频道的情况下再次听到节点的干扰。

摘要： In a burst-mode, high-speed spread-spectrum communications system, faster convergence of a receiver's automatic gain control (AGC) circuit reduces the time required to bring a received signal within the operating range of an operation amplifier and other radio-frequency and digital sections of the receiving system. A gain control circuit includes a coarse-gain feedback loop and a fine-gain feedback loop to improve convergence speed and at the same time maintain the stability of the AGC circuit. The coarse-gain feedback loop quickly brings the received signal, using a large gain signal, to the desired operating range. The fine-gain feedback loop uses a smaller gain signal to gradually smooth the received signal to avoid saturation on the A/D converters.

摘要： A two-wire constant current powered transducer (10) for detecting, integrating and transmitting an acceleration signal (50) received from a piezoelectric crystal (12). The crystal is operatively coupled to rotating machinery (M) such that rotating anomalies correlative of wear or potential failure can be detected early enough for preventative maintenance. The transducer (10) includes two stages (30, 40). The first stage (30) is an integrator which integrates the acceleration to velocity. The second stage (40) is a gain stage. The gain stage operates with a PNP transistor emitter follower to control the output DC bias level and route the integrated acceleration signal back to the control system.
