Incorporating spatial information into BSS algorithms, a class of time-spatial algorithms is derived, which restrict the search range in spatial and improved the convergence rate.
In satellite navigation and positioning system, time is important information for fast and direct acquisition of long cycle code, one of its important aspects is the uncertainty compression of signal's propagation delay to reduce time search range.
In the query above, the search range is defined by the word "some".
"find the first match in the search range and stop."
