Claim 5:
6. An apparatus as claimed in claim 1, wherein the memory and the computer program code are further configured, with the at least one processor, to cause the apparatus, when the program code is executed by the at least one processor, to perform:
sampling received data at said user device, wherein the received data is based on originally transmitted downlink positioning signals, multi-path signals and noise;
cross-correlating the sampled received data with the originally transmitted downlink positioning signals;
initializing parameters that describe the multipath transmissions;
iterating said parameters to improve estimations of said parameters until final parameter estimates are obtained; and
determining an angle of arrival and a time of arrival based, at least in part, on said final parameter estimates.
