METHOD AND SYSTEM FOR IMPROVING TIMING POSITION ESTIMATION IN WIRELESS COMMUNICATIONS NETWORKS |
摘要 |
<p>A method for determining timing positions in a wireless communications system comprises creating a time-domain timing detection window from a preamble of a receiving signal, generating a first vector of correlations between sampling points in the time-domain timing detection window and sampling points of a known preamble, identifying a pivot position from the largest correlation value of the first vector and generating second vectors based on the pivot position, generating a third vector comprising the largest elements of the second vectors; generating a fourth vector comprising sums of elements in the second vectors, generating fifth and sixth vectors comprising a sum of subsets of the third and fourth vectors, respectively, calculating a seventh vector using the fifth and sixth vectors according to a predetermined equation, and selecting an index of one element from the fifth and seventh vectors to be the timing position according to a predetermined rule.</p> |
