摘要： A method of channel encoding and channel decoding in a multiple access communication system wherein the channel decoding requirements increase linearly and not exponentially as the number of users increase. A channel encoder converts alphabetic symbols into a preselected geometric representation of a hexagonal lattice known as a symbol constellation. A channel decoder converts the received symbol constellation into a replication of the alphabetic symbols. Each user has a specially defined symbol set that allows the linear-complexity decoding operation.

摘要： A method and system for conserving battery strength of a mobile node, such as a laptop computer, on a wireless local area network (WLAN). The mobile node transmit symbols, which are units of data, during transmission cycles to maintain a connection with the WLAN. A battery charge level of the mobile node is measured. As the battery charge level drops below pre-defined levels, a frequency of symbol transmission for the mobile node is reduced. The reduction of the frequency of the symbol transmission results in lower power demands by a transmitter chipset of the mobile node. Thus, the mobile node is able to prolong the life of the battery of the mobile node.

摘要： In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, there is a method for determining an uplink transmit power level at which to transmit a current data block over a radio link from the mobile to the base transmitter station. The method evaluates airlink quality measurements in the radio link over a measurement interval, wherein each time a message is sent to the mobile station, it is evaluated whether a specified number of uplink blocks have been transmitted by the mobile station since the start of the measurement interval. Based on the evaluated airlink quality measurement, the method determines the uplink transmit power level that the mobile should be using for the current block, and adjusts the transmit power level, if necessary, for the current block.

摘要： A portable wireless andon communication system and method for use in manufacturing, assembly and other industrial settings. A transmitter station and receiver station are set up for immediate use by simply connecting each to a standard power source. A user needing assistance manually activates a switch at the transmitter station, thus turning on a light and transmitting a corresponding signal to the receiver station. The receiver station receives the signal and turns on a corresponding light and tone generator. The tone generator and light alert indicate to the proper parties the request for a response. A responding party scans transmitter stations for the corresponding light and provides assistance. The switch may be a sensor activated by a change in state indicating that assistance is required. The portable system is easily reconfigured if necessitated by layout changes in a manufacturing line.

摘要： A noise blanker (40, 106) monitors and removes noise from a sampled signal by adaptive filtering (98, 150) the sampled signal to generate trained adaptive filter prediction coefficients. The sampled signal is provided as an output signal when the noise blanker is in a training mode. A noise monitor (34, 154) detects whether noise contained within the sampled signal exceeds a predetermined threshold and provides a control signal in response to the detecting. The noise blanker is placed in a prediction mode for a predetermined amount of time in response to asserting the control signal. A prediction output signal is generated using a plurality of prediction coefficients as an all-pole filter. The prediction output signal has minimal noise content.
