摘要： A method is disclosed to calculate combining weight vectors associated with a received composite information signal comprising at least one data stream transmitted from at least four antennae. The method starts with computing a parametric estimate of an impairment covariance matrix including at least a first impairment term associated with common pilots deployed by the antennae. The first impairment term captures effects of interferences of the common pilots. The impairment covariance matrix further includes a data covariance term capturing effects of the at least one data stream and an interference term caused at least partially by contribution of thermal noise of receiver branches. The impairment covariance matrix includes a second impairment term associated with at least one dedicated pilot. Then the method computes the combining weight vector using the computed impairment covariance matrix. A network device performs such method is also disclosed.

摘要： A method in a network node for estimating a channel from a user node to the network node is provided. The network node receives first pilots. The network node receives (502) additional pilots from the user node. The network node estimates (503) the channel based on the additional pilots. The additional pilots are any one out of: pilots in an existing channel, modified to create space for the additional pilots, and an existing mechanism modified to be used as the additional pilots.

摘要： A method of calculating combining weight vectors associated with a received composite information signal comprising at least one data stream transmitted from at least a first antenna and a second antenna is disclosed. The method starts with computing a parametric estimate of an impairment covariance matrix including at least a first impairment term associated with common pilots deployed by the first antenna and the second antenna respectively. The first impairment term captures effects of interferences between the common pilots, in addition to effects of interferences caused by each common pilot singly. The impairment covariance matrix further includes a data covariance term capturing effects of the at least one data stream and an interference term caused at least partially by contribution of thermal noise of receiver branches. Then the method computes the combining weight vector using the computed impairment covariance matrix.
