APPARATUS FOR RECEIVING SIGNALS VIA CHANNELS |
摘要 |
An apparatus (1) comprising a receiver (20) for receiving signals via channels defined by a channel transfer matrix H and a transmitter (10) is provided with a channel estimator (30) for generating first and second channel estimation information and a correlator estimator (31) for correlating the first and second channel estimation information with each other and for, in response to a correlation, generating a correlation factor and a transmitting feedback unit (32) for, in dependence of the correlation factor, estimating eigenparameters of a covariance matrix HH<H> and for, in response to an estimation, generating feedback information and a receiving feedback unit (33) for receiving the feedback information for adjusting the transmitter (10), to avoid complex matrix processes and to get the feedback information in a simple way. A power estimator (34) estimates a first and second power value for the first and second channel estimation information for normalizing the correlation factor. The estimated eigenparameters comprise estimated eigenvalues and/or estimated eigenvectors. |
