摘要： A method and apparatus for channel coding and rate matching of the Physical Uplink Control Channel (PUCCH) and the Physical Downlink Control Channel (PDCCH) is disclosed that uses convolutional encoding to code the control channels. Rate matching is performed using a circular buffer based rate matching algorithm. A rate matching module may contain a single interleaver or may alternatively comprise a plurality of sub-block interleavers. Interleaved coded bits may be stored in the circular buffer in an interlaced format, or output streams from separate sub-block interleavers may be stored contiguously. When a plurality of sub-block interleavers are used, different interleaving patterns may be used. Rate matching may use bit puncturing or repetition to match the rate of the available physical channel resource. Rate matched output bits may be interleaved using a channel interleaver.

摘要： A wireless communication apparatus which uses fast Fourier transforms (FFTs) in an orthogonal frequency division multiplexing (OFDM) receiver which incorporates a beam space antenna array. The beam space antenna array may be implemented with a Butler matrix array. The beam space antenna array may be a circular array, vertical array, or a combination of both circular and vertical arrays, for providing the desired angular antenna coverage. In one embodiment, the antenna array is optimized because the FFTs are linear invariant transform operators, whereby the order of operations in the OFDM receiver can be interchanged.

摘要： A multiple-input multiple-output (MIMO) beamforming-based single carrier frequency division multiple access (SC-FDMA) system is disclosed. At the transmitter, a fast Fourier transform (FFT) is performed on transmission data to generate frequency domain data. The frequency domain transmit data is mapped to assigned subcarriers. An inverse fast Fourier transform (IFFT) is performed on the transmit data mapped to the assigned subcarriers to generate time domain transmit data. The time domain transmit data is transmitted via antennas. At a receiver, an FFT is performed on the received data to generate frequency domain received data. Subcarrier demapping is performed to extract data mapped on the assigned subcarriers. A channel estimator generates a channel matrix which is decomposed into U, D and VH matrices. A channel distortion and interference between transmit and receive antennas are equalized based on the decomposed channel matrices to the extracted frequency domain received data.

摘要： A method and apparatus for decomposing a channel matrix in a wireless communication system are disclosed. A channel matrix H is generated for channels between transmit antennas and receive antennas. A Hermitian matrix A=HHH or A=HHH is created. A Jacobi process is cyclically performed on the matrix A to obtain Q and DA matrixes such that A=QDAQH. DA is a diagonal matrix obtained by singular value decomposition (SVD) on the A matrix. In each Jacobi transformation, real part diagonalization is performed to annihilate real parts of off-diagonal elements of the matrix and imaginary part diagonalization is performed to annihilate imaginary parts of off-diagonal elements of the matrix after the real part diagonalization. U, V and DH matrixes of H matrix are then calculated from the Q and DA matrices. DH is a diagonal matrix comprising singular values of the H matrix.

摘要： The present invention is related to a method and system for optimization of channel estimation and synchronization in an Orthogonal Frequency Division Multiplexing (OFDM) Multiple-Input Multiple-Output (MIMO) wireless communication system. In accordance with the present invention, all of the training sequences are simply constructed based on a basic code by cyclically shifting the basic code. The training sequences are transmitted from different antennas in parallel without performing inverse fast Fourier transform. As a result, there is no peak-to-average ratio problem. Channel estimation is performed in each receiver based on the samples before fast Fourier transform and the maximum-likelihood estimate of channel response in time domain is then mapped into the frequency domain. The channel estimation is not only very simple in implementation, but also very efficient in computation.
