Title:
METHOD FOR ESTIMATING TIMING OFFSET IN RECEIVER IN MOBILE COMMUNICATION SYSTEM AND APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2015/130047
Kind Code:
A1
Abstract:
The present invention relates to a method for estimating timing offset of a first user in a receiver which supports a VAMOS technique and receives a burst through a wireless channel in a mobile communication system, the method comprising: the first step of determining a received signal matrix by using a plurality of reception training symbols included in the burst and located after predetermined numbers of symbols from the timing offset; the second step of determining an LS channel estimation matrix in which the first user and a second user are combined, by using information on a transmission training symbol allocated to the second user and information on a transmission training symbol allocated to the first user; the third step of performing inner product calculation on the LS channel estimation matrix in which the first and second users are combined and on the received signal matrix so as to calculate a plurality of combined likelihood values; and the fourth step of selecting timing offset so as to have the maximum value among the plurality of combined likelihood values.
