摘要： Methods and apparatus are provided for inserting data symbols and pilot symbols in an OFDM (orthogonal frequency division multiplexing) transmission resource utilizing frequency hopping patterns for the data symbols and/or the pilot symbols. Data symbols and pilot symbols are allocated for down link (base station to mobile station) and up link (mobile station to bases station) transmission resources in a two-dimensional time-frequency pattern. For each antenna of a MIMO-OFDM (multiple input multiple output OFDM) communication system, pilot symbols are inserted in a scattered pattern in time-frequency and data symbols are inserted in an identical frequency-hopping pattern in time-frequency as that of other antennas.

摘要： A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords ci, where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals, and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets Sl for each codeword cl of the codebook C. Each codeword subset Sl defines L codewords cj, which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset Sl are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.

摘要： A method and system are provided for minimizing errors by retransmitting packets in a multiple-input-multiple-output (MIMO) space-time coded packet radio. A packet is transmitted using a first STC code mapping, the mapping including well-known symbol operations, and optional signal weighting. When transmission errors are detected the packet is re-transmitted using STC code mappings selected in turn from a deterministic sequence of STC code mappings. The STC code mappings are chosen in accordance with one or more principles.

摘要： Although orthonormal space-time coding matrices provide for optimal communication system performance in that associated correlation matrices include no non-zero off-diagonal elements, unity code rate orthonormal coding matrices are difficult to identify for arbitrary communication network equipment. According to embodiments of the present invention, non-orthonormal space-time coding matrices, for which associated correlation matrices include non-zero off-diagonal elements, are used to encode data symbols. The non-orthonormal space-time coding matrices are more easily determined, and undesirable effects of the non-zero off-diagonal components are reduced by selecting a coding matrix from among a number of such matrices. For example, a particular space-time coding matrix may be selected from a number of generated space-time coding matrices based on a number of non-zero off-diagonal elements or a power of a trace of the associated correlation matrices.
摘要翻译：虽然正交空时编码矩阵提供了最佳的通信系统性能，因为相关联的相关矩阵不包括非零非对角线元素，单位码率正交编码矩阵难以识别任意通信网络设备。根据本发明的实施例，用于相关联的相关矩阵包括非零非对角元素的非正交空时编码矩阵用于对数据符号进行编码。非正交空时编码矩阵更容易确定，并且通过从多个这样的矩阵中选择编码矩阵来减少非零非对角分量的不期望的影响。例如，可以基于非零非对角元素的数量或相关联的相关矩阵的轨迹的幂来从多个生成的空时编码矩阵中选择特定时空编码矩阵。
