View page
US Patent:
20200014490, Jan 9, 2020
Filed:
Sep 20, 2019
Appl. No.:
16/577624
Inventors:
Sri BHAT - Boyds MD, US
Bala SUBRAMANIAM - Potomac MD, US
Yanlai LIU - Rockville MD, US
Assignee:
Hughes Network Systems, LLC - Germantown MD
International Classification:
H04L 1/00
G06F 12/06
G11C 7/10
G11C 7/18
Abstract:
A deinterleaver device, a method for deinterleaving, an interleaver device, and a method for interleaving are disclosed. The method for deinterleaving includes: providing a memory and a stream count for a frame; virtually dividing the memory into equal sections, wherein a section count equals the stream count; calculating a write address for a sample of the samples based on a location of the sample in the frame and a correspondence of the location to one of the sections; receiving the sample; and writing the received sample to the write address, wherein the calculating and the write address corresponds to a correct deinterleaving location in one of the sections for the sample.

Filed:
Aug 7, 2018
Appl. No.:
16/057726
Inventors:
- Germantown MD, US
Yanlai Liu - Rockville MD, US
International Classification:
H03M 13/35
H04L 12/26
H04L 5/00
H04L 1/20
H04L 1/00
H03M 13/11
H03M 13/00
H03M 13/37
Abstract:
Systems and methods for ACM trajectory include receiving data at a communications receiver; decoding the received data based on a selected MODCOD; monitoring a number of iterations used to decode the data using the selected MODCOD; comparing the number of iterations used to decode the data using the first selected MODCOD to a reference number of iterations; and adjusting a SNR threshold value for the selected MODCOD where the number of iterations used to decode the data using the first selected MODCOD is greater than the reference number of iterations.

US Patent:
20180191463, Jul 5, 2018
Filed:
Dec 28, 2017
Appl. No.:
15/856650
Inventors:
- Germantown MD, US
Yanlai LIU - Rockville MD, US
International Classification:
H04L 1/00
H04W 28/04
Abstract:
A system and method for improving forward error correction efficiency in a communication network. The system and method employ a controller configured to evaluate a plurality of frames to identify a first type of the plurality of frames having a first frame processing characteristic pertaining to a first type of frame iteration processing performed by a terminal of the communication network and a second type of the plurality of frames having a second frame processing characteristic pertaining to a second type of frame iteration processing performed by the terminal. The controller is further configured to arrange a plurality of the first type of frames and at least one of the plurality of the second type of frames in an alternating order within a transmission window for transmission to the terminal.

Novel Ldpc Decoder Design To Significantly Increase Throughput In Asic By Utilizing Pseudo Two Port Memory Structure

US Patent:
20180150253, May 31, 2018
Filed:
Nov 25, 2016
Appl. No.:
15/361227
Inventors:
- Germantown MD, US
Mustafa EROZ - Germantown MD, US
Yanlai LIU - Germantown MD, US
Sri BHAT - Germantown MD, US
International Classification:
G06F 3/06
G11C 8/10
G11C 7/22
G11C 7/10
G06F 12/06
H03M 13/11
Abstract:
A method and apparatus allows single port memory devices to be accessed as pseudo two port memory devices. An access table is created to map the single port memory device to a single port even bank and a single port odd bank. The single port memory device is then accessed based on the mapping. An initial number of entries from the access table are retrieved in order to read addresses in the memory device until a predetermined delay expires. Simultaneous operations are then performed to read from rows in the memory device and write to rows in the memory device. Once all memory addresses have been read, write operations are sequentially performed in rows of the memory device based on the remaining entries of the access table.

US Patent:
20160080802, Mar 17, 2016
Filed:
Sep 11, 2014
Appl. No.:
14/483400
Inventors:
- Englewood CO, US
Yanlai Liu - Rockville MD, US
International Classification:
H04N 21/438
H04N 21/647
H04N 21/4402
H04N 21/44
H04N 21/61
Abstract:
A system includes an antenna and a receiver. The antenna receives an encoded satellite signal having a plurality of frames. The receiver receives the satellite signal from the antenna and iteratively processes each frame a predetermined number of times. The number of times the frame is processed is based at least on part on a characteristic of the frame. Moreover, the receiver terminates frame processing earlier if a condition, associated with the processing of the frame, exists. An example receiver includes a decoder that decodes the satellite signal and extracts data from at least one frame by iteratively processing each frame the predetermined number of times. The receiver further includes a controller that generates a control signal representing the predetermined number of times the decoder is to iteratively process each frame. The controller generates the control signal based at least in part on a characteristic of the frame.
