Patent number: 10243651Abstract: 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.

Patent number: 9621205Abstract: 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.Type: GrantFiled: March 25, 2016Date of Patent: April 11, 2017Assignee: VT IDIRECT, INC.Inventors: Ronggang Qi, Baoyan Ding

Patent number: 9621204Abstract: 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.Type: GrantFiled: March 25, 2016Date of Patent: April 11, 2017Assignee: VT IDIRECT, INC.Inventors: Ronggang Qi, Sahana Raghunandan

Patent number: 9614558Abstract: 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.Type: GrantFiled: March 25, 2016Date of Patent: April 4, 2017Assignee: VT IDIRECT, INC.Inventors: Ronggang Qi, Baoyan Ding
