  • Patent number: 7035648
    Abstract: A method of synchronizing measurement of a mobile station location with communications service includes performing communications service between the mobile station and a base station, transmitting a synchronization message from the mobile station to the base station to indicate that the mobile station will be unavailable for communications service during a selected time interval, measuring the mobile station location from the mobile station during the selected time interval, and resuming communications service between the mobile station and the base station.

  • Publication number: 20060068745
    Abstract: A circuit including an analog to digital converter and a processor is disclosed. The analog to digital converter may be configured to generate a plurality of samples from a received signal in response to a reference signal. The processor may be configured to designate one of an early sample of the samples and a late sample of the samples as an ideal sample in response to a first timing error of an on-time sample of the samples being greater than one-half a sample period of the received signal.

  • Patent number: 6370672
    Abstract: The present invention comprises methods and apparatus for determining the rate at which data was encoded when such data is received at a receiver. According to the present invention, the rate is determined by computing, for a plurality of possible rates, a final test statistic based on a plurality of measures. The final test statistics are compared and based upon certain selection criteria (for example, without limiting the foregoing, which final test statistic corresponds the highest value), the rate is selected. In the preferred embodiment, the measures comprise statistics based on the cyclical redundancy check, Viterbi metrics, re-encoded symbol error rate, and distance to next largest Viterbi metric.

  • Patent number: 5872816
    Abstract: A system and method of blind channel estimation to receive a signal burst over a communications channel; divide the signal burst into a prescribed number of groups of symbols; hypothesize all possible transmitted data sequences or each group; generate a corresponding channel estimate for each possible data sequence; determine an error measurement for each corresponding channel estimate; select a number of the corresponding channel estimates for each group from amongst the corresponding channel estimates, the number of the corresponding channel estimates being selected for having smaller error measurements than remaining corresponding channel estimates not selected; identifying a best channel estimate for each group from amongst the number of the corresponding channel estimates having been selected for each group; and reviewing the best channel estimate having been identified for each group and reidentifying best channel estimates for some of the groups so as to increase smoothness of a curve in two-dimensiona
