  • Patent number: 10243651
    Abstract: A mesh receiver, computer readable storage medium and method for a very small aperture terminal (VSAT) performing communications in a satellite-based network. The mesh receiver includes a receiver that receives a plurality of TDMA mesh carriers simultaneously in the network in plural channels. The mesh carriers have a transmitted frequency, transmitted gain, and transmitted timing that is unknown to the mesh receiver. The mesh receiver also includes circuitry configured to blindly derive gain, frequency, and timing values from the received mesh carriers, and a demodulator that demodulates the received TDMA mesh carriers and generates demodulated bursts for packets of the communications based on the blindly derived gain, frequency, and timing values.

  • Patent number: 9912606
    Abstract: An apparatus and method of communication in a network includes a hub having a burst time plan generating section to generate a burst time plan including time slot allocation information that allocated transmission time slots in a subsequent frame to remote terminals. The allocation information identifies at least one time slot in the subsequent frame as a dummy time slot assigned to at least one remote terminal already acquired in the network. The hub also includes a transmitter to transmit the burst time plan including the allocation information. A corresponding remote terminal and computer readable media are also discussed.

  • Patent number: 9621205
    Abstract: A device and method for estimating a bias in a frequency estimate of a received signal. Circuitry generates a first signal including a number of sample-blocks, wherein the first signal is shifted in frequency from the received signal by a first frequency shift. Based on the first signal, a second signal and a third signal are generated, by shifting a frequency of each of the samples of the first generated signal by a second frequency shift and a third frequency shift, respectively. For each generated signal, a variance for each sample-block is computed. An average variance of the computed sample-block variances is further calculated and a bias of the received signal is determined as one of the first frequency shift, the second frequency shift, and the third frequency shift, corresponding to the generated signal having the smallest calculated average variance.

  • Patent number: 9621204
    Abstract: An apparatus and method for detecting a burst signal. The apparatus includes circuitry that concatenates a predetermined number of samples and transmits the samples to a first programmable memory tap of a predetermined number of programmable memory taps. For each memory tap, a corresponding partial correlation is computed. A normalized sum of all the partial correlations is multiplexed and transmitted to a predetermined number of multipliers. A peak of the burst signal is determined by computing a summation of the complex multiplications of each multiplier, wherein the determined peak corresponds to a start of the burst signal.

  • Patent number: 9614558
    Abstract: A device and method for unwrapping phase samples of a burst signal. The device generates a set of vectors including phase samples. A first mean and a first variance of the vectors is computed, and a set of unwrapped phase samples of the burst signal are computed by rotating phase samples of the vector having a smallest first variance by a first rotation amount. The set of vectors is updated based on a new phase sample and a second mean and a second variance of the updated set of vectors is computed. Differences between unwrapped phase samples and a number of phase samples included in the vector having the smallest computed second variance are computed. A next unwrapped phase sample is generated by rotating the new phase sample by a second rotation amount corresponding to a median value of the computed differences.
