Abstract:
1. A method for estimating a first and second propagation channel being modelled as a linear superposition of finite number of discrete multipath components following an uncorrelated-scattering wide-sense stationary model, with a receiver, comprising the steps of: accounting for a structure of the first and second propagation channels, wherein the first propagation channel is associated with a common pilot channel and the second propagation channel is associated with a dedicated physical channel, wherein the first propagation channel is transmitted without any beam forming and the second propagation is subject to transmit beam forming, wherein the first and second propagation channels are based on a common structure of corresponding propagation channels, one of the channels comprising two sub-channels including a dedicated physical data channel and a dedicated physical control channel (DPDCH, DPCCH); providing channel estimation of the first propagation channel based on pilots used for computing time varying multipath coefficient c providing channel estimation of the second propagation channel, wherein the time varying multipath complex coefficient c
