20080232488 | WIRELESS COMMUNICATIONS APPARATUS AND METHOD - Detection of information on an OFDM signal involves channel estimation. Following an initial channel estimate, it is desirable to perform smoothing or filtering to achieve a more effective channel estimate. A filter is described which is operable to smooth an initial estimate for a subcarrier by reference to one or more adjacent subcarrier estimates. Extrapolation is used to impose, on a subcarrier, information dependent on one or more other subcarriers in the case that the subcarrier in question is not in use other than use by the filter. | 09-25-2008 |
20080311859 | WIRELESS COMMUNICATION APPARATUS - Channel estimation in a MIMO communications system comprises performing a decomposition of an initial channel matrix estimate associated with a first subcarrier of a plurality thereof defined in the channel to identify eigenvectors associated with that subcarrier of the received signal, and defining a first beamforming transformation to be applied to the received signal on the basis of the eigenvectors. Then, for each of the other subcarriers, an additional decomposition is performed in order to determine a further beamforming transformation for each of said one or more other subcarriers, wherein said additional decompositions are carried out incrementally such that information determined in one of said decompositions contributes to a later executed decomposition. Further described is a method of transmitting from a multiple antenna transmitter defining a plurality of subcarriers in space, and time or frequency, comprising the same iterative process. This transmitting can be carried out using smoothed beamforming applied in accordance with aspects of the invention. | 12-18-2008 |
20090060074 | WIRELESS COMMUNICATIONS APPARATUS - Precoding a plurality of subcarriers in preparation for MIMO transmission is carried out by deriving preceding matrices from available information. When the number of data streams borne by the subcarriers equates to the number of transmit antennas employed in the MIMO transmission, the method comprises deriving, from respective acquired unitary precoder matrices for two of said subcarriers, interpolated precoder matrices for data streams intermediate the two subcarriers. The acquired and interpolated precoder matrices are then applied, as the case may be, at the respective subcarriers. The step of deriving the interpolated precoder matrices comprises determining an overall rotation matrix representing a transformation between the acquired precoder matrices, determining from the overall rotation matrix a further rotation matrix representing a step transformation for interpolation steps between said two subcarriers, and recursively applying said further rotation matrix to derive said interpolated precoder matrices. In the event that the number of data streams is less than the number of transmit antennas employed in said MIMO transmission, the rectangular precoder matrices should first be converted into square unitary matrices. | 03-05-2009 |
