A set of channels is selected based on the results of performance testing and specified criteria. The participant generates data that identifies the selected set of channels and provides that data to other participants of the communications network. The participants communicate over the set of channels, such as by using a frequency hopping protocol. When a specified time expires or monitoring of the performance of the channel set identifies poor performance of the set of channels, the participant selects another set of channels for use in communications based on additional performance testing. By selecting channels based on the initial performance testing and performance monitoring, the communications network adaptively avoids channels with poor performance. | 2011-09-08 |
| 20110216810 | Increased capacity communication links with spectrum sharing - Various embodiments are directed to systems and methods for processing signals comprising a first component and a second component. A bandwidth of the first component may be centered at a center frequency. A bandwidth of the second component may be offset from the center frequency by an offset frequency such that at least a portion of the bandwidth of the second component overlaps a skirt of the first component. In various embodiments, a transmitter may split a single signal to generate the first and second components, shift the frequency of the second component, recombine and transmit the two components. Also, in various embodiments, a receiver may receive the signal and derive the first and second components by correcting for cross-interference. | 2011-09-08 |
| 20110216811 | METHODS AND APPARATUSES FOR DEMODULATING MULTIPLE CHANNEL SATELLITE POSITIONING SYSTEM SIGNALS - Methods and apparatuses are provided which may be enabled within and/or for use with a Satellite Positioning System (SPS) receiver and/or other like apparatuses or device(s) to demodulate a first channel portion of a multiple channel SPS signal based, at least in part, on a second channel portion of the multiple channel SPS signal. | 2011-09-08 |
| 20110216812 | APPARATUS AND METHOD FOR PERFORMING DELAY-LOCKED LOOP OPERATION ON RECEIVING SIGNAL - A method for performing delay locked looping upon a received signal which reduces the asymmetry of auto-correlation function resulting from sampling is provided. The received signal is a spread spectrum code signal, and the method includes: generating a plurality of replica spread spectrum code signals according to an estimated code phase delay and phase spacing, the replica spread spectrum code signals having phases respectively different from the phase of the received signal; calculating a spread spectrum code error statistics signal according to the replica spread spectrum code signals and the received signal; and adjusting the estimated code phase delay according to the spread spectrum code error statistics signal and a phase difference between a sampled point of at least one replica spread spectrum code signal and a corresponding signal transition point. | 2011-09-08 |
