PROBLEM TO BE SOLVED: To estimate parameters of a wireless communication system which includes at least one base station and at least one remote terminal. SOLUTION: A method and apparatus for estimating the parameters of a wireless communication system includes at least one base station, each of the base stations having (m) antenna elements (101), the parameters being one or more of: the time alignment, the frequency offset, and the weight vector for spatial processing. At any stage, some of the parameters may already be estimated. A signal of known characteristics is transmitted and received and (m) received signals (103) at the antenna elements (101). A cost function that is related to the at least one or more parameters of the second set is determined using a copy signal determined from samples of the received signals (103), estimates of one or more parameters, if available, known characteristics of transmitted first signal. The estimate of the parameters to be determined is obtained by minimizing the cost function.
