摘要： The angular position of an output gear can be determined from the phase difference between the angular positions of pinions engaged with the output gear. The first pinion can have a K-number of teeth, the second pinion can have an L-number of teeth, and the output gear can have an M-number of teeth. The relationship between K, L, and M can include the following: M is the least common multiple of K and L; and the absolute value of the difference between M divided by K and M divided by L is one. It can also be said that the absolute value of L subtracted from K is a non-zero integer.

摘要： A cluster of communications platforms can comprise a master platform and support platforms. The master platform can partition a data block into data partitions and transmit the data partitions via a short range transmitter to the support platforms. Each support platform can include a high power storage device for powering long range burst transmissions of a subset of the data partitions to a distant receiver. Burst transmissions of data partitions by the same support platform can be separated by a charging time period that allows a high power storage device in the support platform to charge from a relatively low average power Pa a relatively high power burst PB that is sufficient to transmit one of the data partitions to a distant receiver.

摘要： The perceived sample rate at which a DAC can operate can be increased by allowing multiple DACs to process different portions of a digital signal in parallel. In this way, the outputs of multiple DACs can be combined into a single analog signal to achieve the desired speeds and resolutions of the analog output. This parallel processing can be implemented using a time-interleaving technique or a sub-band reconstruction technique. Pre-distortion can be applied to the digital input signal to compensate for degradation detected in the analog output signal. By applying pre-distortion, waveforms having high sampling rates can be efficiently generated.

摘要： Adaptive filtering is used to substantially cancel distortion in radio frequency (RF) signals. Such adaptive filtering can be used in an RF transmitting module to pre-compensate an RF signal with compensation (inverse) distortion to cancel inherent transmission path distortion from the RF signal. Adaptive filtering can also be used in a multi-carrier RF receiving module to cancel from a given carrier signal distortion due to cross talk from adjacent carrier signals. Adaptive filtering in an RF transceiver can be used to cancel from a received RF signal distortion arising from leakage of a transmit signal into the receive path.

摘要： A first device and a second device can include at least one alignment feature and at least one corresponding constraint. The alignment feature and the constraint can be configured to align the first device and the second device when the alignment feature is inserted into the constraint. The alignment feature and the constraint can be further configured to direct relative movement between the first device and the second device due to relative thermal expansion or contraction between the first device and the second device. The directed relative movement can keep the first device and the second device aligned over a predetermined temperature range.

摘要： The present invention is directed to a decision feedback equalizer that implements a multipath delay calculator to determine the delay between a line-of-sight component of a received data signal and a reflection of the line-of-sight component. The determined delay is used to control when decisions are used within the decision feedback equalizer so that the appropriate decisions are delayed until the reflection is received. In this way, the reflection can be substantially removed from the data signal using decisions that were generated when the line-of-sight component was received. Because the correction window is limited to the time when the reflection is received, the number of taps required to perform equalization is greatly reduced resulting in a decision feedback equalizer with less circuitry or logic.

摘要： Techniques for efficient upconversion can process complex input data, such as for example data in an inphase and quadrature form. Half sample interpolation filtering and delay can be performed, and the results can be combined in a quarter-rate upconverter. The quarter rate upconversion can allow one of the half-sample interpolating filtering and the delay to be performed on one of either the inphase and quadrature samples.

摘要： Methods and terminals can use Internet Protocol (IP) packets for waveform independent contention access in a hub-spoke network. In some embodiments, a spoke terminal can transmit a link allocation packet on an uplink when the uplink is available and the spoke terminal has data to transmit. The link allocation packet can be embedded within an IP packet. When the spoke terminal receives the link allocation packet on the downlink, the spoke terminal can transmit one or more IP packets with data, followed by a link release packet. The link release packet can be embedded within an IP packet.

摘要： A technique for decoding low-density parity check codes includes performing a combined check node and variable node calculation. Decoding is initialized using channel likelihood values estimated from a received physical signal. The decoding iteratively updates the variable nodes. Performing a combined check node and variable node calculation can enable reduced memory usage and faster convergence for the decoder.
