The problem of estimating the multipath channel parameters of a new user entering the uplink of an asynchronous direct sequencecode division multiple access (DS-CDMA) system is addressed. The problem is described via a least squares (LS) cost function with a rich structure. This cost function, which is nonlinear with respect to the time delays and linear with respect to the gains of the multipath channel, is proved to be approximately decoupled in terms of the path delays. Due to this structure… CONTINUE READING
