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: 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; determining 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; 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 selecting the timing offset so as to have the maximum value among the plurality of combined likelihood values.
