Patent number: 10812250Abstract: Interference cancellation in a receiver can be used to improve bandwidth efficiency. The transmission of bursts from different terminals scheduled at separate time intervals can overlap partially such that time used for information transmission is optimized. For example, a receiver includes a signal processor including instructions executable to select first data including a first burst and a successive second burst from a transmission. The signal processor demodulates and decodes information from the first burst. The signal processor further generates a remodulated first burst based on recoded and remodulated information and generates second data by subtracting the remodulated first burst from the first data. The signal processor synchronizes with a stored symbol pattern in the second burst; and demodulates and decodes the information from the second burst. With such arrangement, the performance of each link is not affected by the partially overlapping burst.Type: GrantFiled: September 29, 2017Date of Patent: October 20, 2020Assignee: Hughes Network Systems, LLCInventors: Lin-Nan Lee, Liping Chen
