摘要： PROBLEM TO BE SOLVED: To efficiently derive a spatial filter matrix. SOLUTION: In a first scheme, a Hermitian matrix is iteratively derived based on a channel response matrix, and a matrix inversion is indirectly calculated by deriving the Hermitian matrix iteratively. The spatial filter matrix is derived based on the Hermitian matrix and the channel response matrix. In a second scheme, multiple rotations are performed to iteratively obtain first and second matrices for a pseudo-inverse matrix of the channel response matrix. The spatial filter matrix is derived based on the first and second matrices. In a third scheme, a matrix is formed based on the channel response matrix and decomposed to obtain a unitary matrix and a diagonal matrix. The spatial filter matrix is derived based on the unitary matrix, the diagonal matrix, and the channel response matrix. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a device for deriving and using noise estimate for data reception in a wireless communication system.SOLUTION: A noise estimate may be derived for each packet received in a data transmission. Data detection is then performed for each packet using the noise estimate for the packet. For the noise estimation, a first sample sequence and a second sample sequence may be obtained from each receiver used for data reception. A phase offset between the first and second sample sequences is determined and applied to the first sample sequence for each receiver to obtain a third sample sequence for the receiver. A noise estimate may then be obtained based on the differences in electric power between the second and third sample sequences for the at least one receiver.
