20100304779 | POWER CONTROL IN A WIRELESS COMMUNICATION SYSTEM - A method of power control in a wireless communication system, wherein blocks are transmitted from a transmitter to a receiver via a wireless transport channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; detecting if a data block has been received; detecting if received blocks have been successfully decoded; and decreasing the target value when pass blocks are received and increasing the target value when failed blocks are received subject to monitoring a period of inactivity on the transport channel in which no blocks are received. | 12-02-2010 |
20110019754 | POWER CONTROL IN A WIRELESS COMMUNICATION SYSTEM - A method of power control in a wireless communication system wherein blocks are transmitted from a transmitter to a receiver on multiple wireless transport channels. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power, and a mechanism for controlling the target signal quality for transport channels that have been inactive for a predefined period. A corresponding receiver is also provided. | 01-27-2011 |
20120076189 | ESTIMATION OF SIGNAL AND INTERFERENCE POWER - Wireless receiver and method of operating a wireless receiver in a wireless communication network for: receiving a signal, the received signal comprising data containing at least one symbol from a symbol alphabet, the symbol alphabet consisting of complex values that define a direction in the complex plane, the received signal further comprising interference; measuring the variance of a first component of the received signal that is perpendicular to the defined direction in the complex plane; estimating the interference power of the received signal using the measured variance of the first component of the received signal; estimating a total power of the received signal; estimating the power of the at least one symbol of the received signal by subtracting the estimated interference power from the estimated total power of the received signal; and based on the estimated interference power and the estimated power of the at least one symbol of the received signal, performing at least one of the steps of: processing the received signal, and generating control information related to the transmission of a further signal from the wireless receiver. | 03-29-2012 |

The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; determining if received blocks have been successfully decoded; identifying the received blocks as pass or fail blocks; when pass blocks are received, comparing the target signal quality value with the received signal quality value and decreasing the target value only if the target value is greater than the received signal quality value less a margin. | 12-09-2010 |

20100254445 | PROCESSING TRANSMISSIONS IN A WIRELESS COMMUNICATION SYSTEM - Disclosed herein are methods of processing transmissions in a wireless communication system to detect whether a transmission unit contains transmitted data, systems for processing transmissions in a digital communications system to detect the same, receivers for processing transmissions in a wireless communications system and computer readable media implementing a method for processing the same. In one embodiment, a method of processing transmissions in a wireless communication system to detect whether a transmission unit contains transmitted data includes: generating an averaged function of bit reliability indicators from a plurality of received samples and applying a test to compare an average of ln cos h(ยท) (natural logarithm of the hyperbolic cosine) values for the reliability indicators, with a factor proportional to an average signal-to-disturbance ratio of the plurality of samples to determine if the transmission unit contains transmitted data. | 10-07-2010 |

20130281873 | METHOD FOR MEASURING BREATH ALCOHOL CONCENTRATION AND APPARATUS THEREFOR - The present invention relates to a method and apparatus for measuring breath alcohol concentration of a user. A flow of an expired breath sample is passed through a fuel cell sensor giving an output signal proportional to the amount of alcohol present in the breath sample. By measuring the flow rate, the volume of the breath sample may be calculated, whereas the breath alcohol concentration is calculated based on the fuel cell output signal. Both the sample volume and the breath alcohol concentration values are continually updated by integrating the measured instantaneous flow rate and the fuel cell output signal over time. If the user stops blowing, flow compensation is performed to obtain a compensated fuel cell output signal using a stored calibration volume. Hence, an improved method for accurately measuring the breath alcohol concentration of a test person is achieved, capable of handling varied expired volumes of breath, which obviates the need for a sampling mechanism. | 10-24-2013 |

20150335265 | METHOD FOR MEASURING BREATH ALCOHOL CONCENTRATION AND APPARATUS THEREFOR - A method and apparatus for measuring user breath alcohol concentration. A flow of an expired breath sample is passed through a fuel cell sensor giving an output signal proportional to the amount of alcohol present in the sample. By measuring pressure, the volume of the sample may be calculated by integrating pressure over expiration time of the sample, whereas breath alcohol concentration is calculated based on the fuel cell output signal. Both sample volume and breath alcohol concentration values are continually updated by integrating measured instantaneous pressure and fuel cell output signal over time, irrespective of breath sample volume. When the user stops blowing, volume compensation is performed to obtain a compensated fuel cell output signal using a stored calibration volume. Hence, an improved method for accurately measuring breath alcohol concentration of a user is achieved, capable of handling varied expired volumes of breath, obviating the need for sampling mechanism. | 11-26-2015 |
